cross multiply your equation

(1*25)/10= 2.5 minutes

hence, he took 2.5 minutes to blow up one balloon

Answer 2

Answer: 2 minutes and 30 seconds per ballon

Explanation:

First we turn these into fractions to get 10/25

Then we divide both of these by 10 to get 1/2.5

This means we have 2 minutes and half of a minute is 30 seconds which is where we get 2 minutes and 30 seconds
