Question

Liam has 9/10gallon of paint for painting the birdhouses he sell at the craft fair .Each birdhouse requires 1/20 gallon of paint .How many birdhouses can Liam paint ?

Answer 1

You would make each fraction have the same denominator. 9/10 is the same as 18/20. If one birdhouse takes 1/20 of paint, then he can paint 18 birdhouses with 18/20 of a gallon. I hope this helps!
