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
- Assume that the number of kids in the class is x
∴ The number of kids likes the chips = × x =
∵ 4th of the class likes pennies
- 4th means
∴ The number of kids likes pennies = 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 =
∵
∴ The number of kids left =
∴ The number of kids left = x
∵ 7 kids left
- Equate x by 7 and find x
∴ x = 7
Multiply both sides by 4
∴ x = 28
