You do it like this: 15/100 = 21/x and cross multiply like this: 15x = 2100 ((Divide by 15 on both sides) x = 140 (This is your answer) I hope this helps you! Have a great night!
The answer would be h+(h+2.5)=22 The h represents Williams hours and the h+22 represents jose's hours. Together, they add to 22 hours :) Hope this helps!
