Question

Three sevenths of a children's choir are boys. If there are 12 boys in the choir, how many children, c, total are in the choir? Solve for c.

Answer 1

28 kids are in the choir. Its 3 * 4 = 12. Then Its 3/7 * 4 = 12/28. Ther you gooooo.

Answer 2

Here c represents the total number of children in choir.

As per the statement:

Total number of boys in choir = 12

It is also given that: Three sevenths of a children's choir are boys.

⇒ Total number of boys =
`(3)/(7) c`

or

`12 = (3)/(7)c`

By cross multiply we have;

84 = 3c

Divide both sides by 3 we have;

c = 28

Therefore, the total number of children in choir is 28 children
