Question

Lydia bought 2 ½ gallons of paint and used 1 ½ gallons of paint. What fraction of the paint did she use?

Answer 1

3/5 is used

2 1/2 gallons can be expressed as 5/2
1 1/2 gallons is the same as 3/2the fraction used is amount used over total amount

So (3/2)/(5/2) the 2 s cancel leaving you with 3/5
