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