Question

3 tenths of the pies that Jackie’s bakery sold last week were blueberry pies 4 tenths if the pies were blackberry pies. How many pies were either blueberry or blackberry pies?

Answer 1

7 tenths were either blueberry or black

Answer 2

We can find this simply by adding them together. 3/10+4/10=7/10. Then, subtract 7/10 from 1, which is the total amount of pies. The answer is 3.

Hope this helps!
