Explanation:
Fred the clown can create 20 animals balloons for every 15 minutes. Let us calculate the rate at which he can make the balloons.
Since he makes 20 balloons for 15 minutes
he will make ? balloons for 1 minutes
cross multiply
20/15 = 1.333 minutes
The question ask to use equivalent ratios minutes number to calculate for 15 , 6, and 45 ballons
For 15 ballons
Since 20 balloons = 15 minutes
15 balloons =

minutes
for 6 ballons
Since 20 balloons = 15 minutes
6 balloons =
90/20
= 4.5 minutes
For 45 balloons
Since 20 balloons = 15 minutes
45 balloons =
