It takes two apples to make an apple pie. If a chef bought nine apples, the last pie
defon

Hey!

-------------------------------------------------

If a chef bought 9 apples and each pie takes 2 apples then all we have to do is divide.

9 / 2 = 4.5

4 full pies can be made with 9 apples.

4 x 2 = 8 (apples were used to make 4 pies.)

9 - 8 = 1 (apple remaining)

If one pie needs 2 apples, subtract.

2 - 1 = 1 (pies the chef needs to make the last one)

-------------------------------------------------

Answer: The last pie would need 1 more apple.

-------------------------------------------------

Hope This Helped! Good Luck!
