Question

The ratio of cakes to cookies in the bakery was 3:5. If there were 90 cakes, how many cookies were in the bakery?

plz help

Answer 1

150 cookies

Explanation:

Using the ratio as an equation we can divide 90 by 3 to find the common multiple used to simplify this equation into a more usable ratio.

3 : 5 90 : 5x (x is the common multiple)

90 / 3 = 30, so x is 30

Then we multiply both sides of the original ratio by the common multiple to get our answer.

3 : 5 is equal to 90 : 150
