Question

1) Rob is making cupcakes. The recipe calls for 1 2/3
cups of sugar for each batch. He plans to make
2 1/2 batches. His friend Callie thinks he will need 4
1/2 cups of flour to make the cupcakes. Is she
correct? Explain and justify your answer.

Answer 1

Answer:

She is incorrect

Step-by-step explanation:

1 2/3 = 5/3

2 1/2 = 5/2

5 5 25

-- x -- = --

3 2 6

25/6 = 4 1/6

4 1/2 ≠ 4 1/6

Therefore, she is incorrect
