Answer:Here we will learn how to make the ratio in simplest form.

1. A ratio between two quantities of same kind and in the same units is obtained on dividing one quantity by the other and has no unit. The ratio is independent of the units used in the quantities compared.

2. The ratio must always be expressed in its simplest form or in its lowest terms.

A ratio is said to be is the simplest form or in the lowest term if two quantities of a ratio (i.e., antecedent and consequent) have no common factor (i.e. antecedent and consequent are co-prime) other than 1 (or their HCF is 1.)

For example:

(i) The ratio between 36 kg and 24 kg = (36 kg)/(24 kg)

= 36/24, [both numerator and denominator are divided by 12]

= 3/2

= 3 : 2.

(ii) The ratio between 5 kg and 15 kg = (5 kg)/(15 kg)

= 5/15, [both numerator and denominator are divided by 5]

= 1/3

= 1 : 3.

3. If in a ratio the number or quantities are of the same kind but in different units, then we must convert them number or quantities into same unit. Generally, the bigger unit of the ratio is converted into smaller unit.

For example:

(i) The ratio between 800 g and 1.2 kg = (800 g)/(1200 g)

= 800/1200, [since 1.2 kg = 1.2 × 1000 gm = 1200 gm]

= 8/12, [both numerator and denominator are divided by 4]

= 2/3

= 2 : 3.

(ii) The ratio of 5 cm and 60 mm = (50 mm)/(60 mm), [since 5 cm = 5 × 10 mm = 50 mm]

= 50/60, [both numerator and denominator are divided by 10]

= 5/6

= 5 : 6.

4. If each term of a ratio is multiplied or divided by the same non-zero number (quantity), the ratio remains the same.

For example:

The ratio of 18 and 24= 18 : 24 = 18/24

Now, 18/24 = (18 × 6)/(24 × 6) = 108/144  or, 18 : 24 = 108 : 144.

Again, 18/24 = (18 ÷ 6)/(24 ÷ 6) = 3/4 or, 18 : 24 = 3 : 4.

5. The order of the quantities (terms) in a ratio (P : Q) is important. By reversing the antecedent and the consequent of a ratio, a different ratio is obtained (i.e., Q : P).

For example:

(i) The ratio 5 : 7 is different from the ratio 7 : 5.

(ii) 6 : 11 is different from 11 : 6.

The different types of examples along with the explanation will help us how we usually express the ratio in simplest form.

Answer:

The sum of two consecutive number is 55'which is the largest number? So the numbers are 27 and 28.

Step-by-step explanation:

If we say \(x\) is the first number, then the next consecutive number will be \(x+1\).

Using this, we can make an equation.

\(x+(x+1)=55\)

\(2x+1=55\)

\(2x=54\)

\(x=27\)

And so we know that the two consecutive numbers are 27 and 28.

Hope this helps.

Answer:1,440 cubes

Step-by-step explanation:

A=LxHxW

6 inches=36 cubes

The width is 5 of those cubes

36x5=180

The height is 8 of the cubes

180x8=1440

It would take 1440 of those cubes to completely pack the prism without any gaps or overlays

Step-by-step explanation:

Let's assume the amount Mackey initially invested in the 6% account is x dollars.

According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.

The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.

The total interest earned in the year is given as $737.50, so we can set up the equation:

0.06x + 0.085(x + $1000) = $737.50

Simplifying the equation:

0.06x + 0.085x + 0.085($1000) = $737.50

Combining like terms:

0.145x + $85 = $737.50

Subtracting $85 from both sides:

0.145x = $737.50 - $85

0.145x = $652.50

Dividing both sides by 0.145:

x = $652.50 / 0.145

x ≈ $4500

Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.

$4500

$4500

$4500

$4500

Answer:

The second graph

Step by Step

First, note down the points given.

(-2, -1) etc

Then find the points on the graphs and see if the line of the graph goes through the point.

(-2,-1): both lines go through this point

(0,0) both lines go through this point

(2,1) only the second graph goes through this point

Therefore, the second graph is the correct answer. You can check the last point if you want to double check.

Answer:

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

Answer:

I believe the answer is D.

Answer: Part: Rotten mangoes question
Whole: Penguin question, shirts in a closet question

Percentage: Household pets question, perfect attendance question

Step-by-step explanation:

Questions that ask for the percentage of something are always percents (household pets and perfect attendance).  "How many shirts are in the closet?" means it is a whole because it isn't asking for a particular type of shirts like "How many long sleeve shirts are in the closet?".  The question about penguins is also a whole because it isn't asking "How many emperor penguins are in the zoo?" (which is a specific kind of penguins).  The question about mangoes is a part because it isn't asking for "How many mangoes are in the box", (which would be a whole because it is not specified to the type of mangoes), but it is asking for a specific kind of the mangoes (rotten mangoes).  

Answer:

192 hours per day / 8 hours per person per day = 24 people

Step-by-step explanation:

Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:

720 person-days x 8 hours = 5,760 hours

To complete the project in 30 days, the total number of hours needed per day is:

5,760 hours / 30 days = 192 hours per day

Answer:

7:20 p.m.

Step-by-step explanation:

First, we can find the distance that each friend will be from their house at the time when they meet each other.

To find this, we can multiply the ratio \(8 \text{ mi} : 7 \text{ mi}\) by a constant such that the sum of both numbers in the ratio is 20, since the friends' houses are 20 miles apart. Solving for this constant:

\(\dfrac{20}{7 + 8} \\ \\ = \dfrac{20}{15} \\ \\ \boxed{=\dfrac{4}{3}}\)

Multiplying the constant by both sides of the ratio:

\(\dfrac{4}{3}\left(8 \text{ mi}) : (7 \text{ mi}\right)\dfrac{4}{3}\)

\(\boxed{= \dfrac{32}{3} \text{ mi} : \dfrac{28}{3} \text{ mi}\right)}\)

So, we know that the first friend will have traveled 32/3 or 10 2⁄3 miles when they meet, and the second friend will have traveled 28/3 or 7 1⁄3 miles.

Now, to calculate what time they will meet, we can divide how far one of the friends has traveled by how fast they were traveling. This will give us the minutes it will take them to get to the meeting place. We can then add that amount of minutes to 6:00 p.m. to calculate when they will meet.

I will use the fast friend (traveling at 8 mph).

\(\dfrac{32}{3} \text{ mi} \cdot \dfrac{60 \text{ min}}{8 \text{ mi}}\)

— Also note that I substituted 1 hour for 60 minutes in the mph ratio.

\(= \dfrac{32}{3} \not\text{mi} \cdot \dfrac{60 \text{ min}}{8 \not\text{mi}}\)

\(= \dfrac{32 \cdot 60}{3 \cdot 8} \text{ min}\)

\(= \dfrac{32}{8} \cdot \dfrac{60}{3} \text{ min}\)

\(= 4 \cdot 20 \text{ min}\)

\(\boxed{= 80\text{ min}}\)

Adding those minutes to 6:00, noting that 80 min = 1 hr 20 min:

\(\text{ } \ \, 6\!:\!00 \text{ p.m.}\\\underline{+ 1\!:\!20}\\\\\text{ }\, \boxed{7\!:\!20 \text{ p.m.}}\)

So, the friends will meet at 7:20 p.m.

Answer: The answer is D

Step-by-step explanation:

Since there are 20 people in the 53-65 range, we can add that to the number of people in the 14-26 range which is 60.

The sum of both of those then gives us 80 which is the same amount as the 40-52group

Answer:

40-52 & 53-65

Step-by-step explanation:

we know our age groups mean that there can be more than 120 in number as the 27-39 age group can only be 2 groups. Which conceals the fact that we need it two

40-52 is an age group which has 80 in number and below it the

“  14-28 age group “

60 in age group.

12% is equivalent to 12/100.  This reduces to 3/25.  Thus, 3/25ths of the students are left-handed.  The corresponding fraction for the right handed people is (25-3)/25, or 22/25ths.  There are more right-handed people (22/25ths) versus left-handed people.

Step-by-step explanation:

Quite easy, you can use substitution

First look at the simplest row that can be solved by itself

row 2:

2strawberries +4 = 10

2 strawberries= 6

1 strawberry = 3

Row 3: Strawberry(3)+ orange=8

1 orange= 5

Rpw 4: 14= 1coconut +orange(5)

1 coconut= 9

Row 1: Coconut(9)+ watermelon+ coconut(9)= 21

2 coconut(18)= 21

1 watermelon = 3
