Question

Half of the class likes chips 4th of the class likes pennies and the 7kids left want waterfront how many kids are in the class

Answer 1

There are 28 kids in the class

Step-by-step explanation:

If an object is divided into different part, then

• The total of all parts is 1
• To find a missing part subtract the sum of the other parts from 1

∵ Half of the class likes chips

- Have means $\frac{1}{2}$

- Assume that the number of kids in the class is x

∴ The number of kids likes the chips =  $\frac{1}{2}$ × x =  

∵ 4th of the class likes pennies

- 4th means $\frac{1}{4}$

∴ The number of kids likes pennies =  $\frac{1}{4}$ x

∵ The rest of the class want waterfront

- Find the rest of the class in terms of x by subtracting the sum

  of the two given fractions from the number of kids

∴ The number of kids left = $x-(\frac{1}{2}x+\frac{1}{4}x)$

∵ $\frac{1}{2}x+\frac{1}{4}x=\frac{3}{4}x$

∴ The number of kids left = $x-\frac{3}{4}x$

∴ The number of kids left =  $\frac{1}{4}$ x

∵ 7 kids left

- Equate  $\frac{1}{4}$ x  by 7 and find x

∴  $\frac{1}{4}$ x = 7

Multiply both sides by 4

∴ x = 28

There are 28 kids in the class
