Question

Molly is baking for the moms and muffins event at her school. She will bake 4 batches of banana muffins. She needs 1 3/4 cups of bananas for each batch of muffins.

PART A

Molly completed the multiplication below and said she needed 8 cups of bananas for 4 batches of muffins. What is mollys error?

4 x 1 3/4 = 4 x 8/4 = 32/4 =8

PART B

What is the correct number of cups molly needs for 4 batches of muffins? Explain how you found your answer.


Answer both PART A and PART B

Answer 1

I did the math to figure out how many cups are needed hopefully this helps

Answer 2

Part A = She incorrectly add 1 (4/4) with 3/4, so instead of getting 7/4 she got 8/4.
Part B=She needs 28/4 (7) cups for 4 batches because 4/1x7/4=28/4.
