Answer:
48
Step-by-step explanation:
Wrong : right
1 :12
Multiply by 4 because she gets 4 problems wrong
1*4 : 4*12
4 :48
If she gets 4 problems wrong, she gets 48 problems right
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.
