Question

Zoey made 5 and 1/2 cups of trail mix for a camping trip. She wants to divide the trial mix into 3/4 cup servings. Ten people are going on the camping trip. Can Zoey make enough 3/4 cup servings so each person on the trip has one serving?

Answer 1

No she can't.  We could divide 5 1/2 cups by 3/4 cups but there is an easier way.

Let's change 3/4 to .75 and multiply by 10 since we need 10 servings.

.75 x 10 = 7.5  so she would need 7.5 cups or 7 1/2 cups
Since she only has 5  1/2 cups,  she does not have enough.
