Question

As a sporting goods store,3/10 of all the items are baseball items and 1/3 of all the items are football items. What fraction of the total number of items in the store are baseball or football items?

Answer 1

Find a common denominator first... which would be 30

3/10×3= 9/30 baseball items

1/3×10= 10/30 football items

10/30+9/30= 19/30 total football and baseball items

19/30 doesn't simplify, so the answer is 19/30
