Question

A recipe for biscuits says to mix 6 cups of flour with 2 cups of milk.

How many cups of milk would you need for 5 cups of flour?

Answer 1

`(5)/(3)` or
`1(2)/(3)` cups of milk

Explanation:

So if you have the ratio of 6 cups of flour to 2 cups of milk you can make this the fraction:
`(6)/(2)` and then for the 5 cups of flour to 'x' cups of milk the fraction would be:
`(5)/(x)`

To solve for 'x', let the 2 fractions equal each other and cross multiply.

`(6)/(2) = (5)/(x)`

`x = (2*5)/(6) = (10)/(6) = (5)/(3) = 1(2)/(3)`

So you would need
`(5)/(3)` or 1 and
`(2)/(3)` cups of milk for 5 cups of flour.
