Answer:
Part A = D
Part B = B
Step-by-step explanation:
Since we know that Harry needs 2 1/4 Cups of flour for 1 batch of cookies and he needs 10 batches, we simply multiply 2 1/4 or 9/4 by 10 -->
9/4(10) otherwise known as 2 1/4 x 10 = c
--> We then solve by converting 9/4(10) = 90/4
--> Simplify
45/2 = 22 1/2
--> Thus you have your answers
