Question

Audrey has some guppies in a fish tank. The ratio of the orange guppies to silver guppies is 3 : 5. She has 12y orange puppies. Write the number of silver guppies she has in terms of y.

Answer 1

Should be y=20

Explanation:

Answer 2

We solve:

`(3)/(5) = (12y)/(number \: of \: silver \: guppies) \: or \\ \\ 3 * (number \: of \: silver \: guppies) \: \\ = 60y \\ \\ this \: means \: the \: number \: of \: \\ silver \: guppies \: in \: terms \: of \: y \: is \: \\ (60y)/(3) = 20y`
