Question

Shaq painted 21 portraits every 35 minutes. At that rate, how long, in minutes, will it take to paint 15 portraits?​

Answer 1

25 minutes

Explanation:

To find how long each portrait takes divide 35/21. This equals about 1.67 minutes per painting. Multiply this by 15 to get the answer: 25 minutes.

Answer 2

25 minutes

Explanation:

We find the unit rate.

21 portraits per 35 minutes = 21/35 = 3/5 portraits per minute

15 portraits / (3/5 portrait/minute) = 25 minutes
