Question

Betsy's mom likes to bake.

She uses 2 1/2 cups of flour in one batch of her famous chocolate chip cookies.
She needs to bake 3 1/4 batches for her annual cookie swap. She has 7 cups of
flour at home.
Does she have enough flour?
If so, how much extra will she have? If not, how much
more does she need?

Answer 1

No

Explanation:

I did it

Answer 2

She doesn't have enough flour

8 1/8 - 7 = 1 1/8 cups more of flour

Explanation:

2 1/2 = 5/2

3 1/4 = 13/4

5*13 = 65

2*4 = 8

65/8 = 8 1/8

She doesn't have enough flour

8 1/8 - 7 = 1 1/8 cups more of flour

Hope this helps! :)
