Answer:
5 cups of walnuts are needed.
Step-by-step explanation:
This question can be solved using a rule of three.
One batch of walnut muffins uses 1 1/3 cups of walnuts.
So one batch of walnut muffins uses [tex]1 + \frac{1}{3} = \frac{4}{3}[/tex] cups of walnuts.
How many cups of walnuts are needed to make 3 3/4 batches of muffins?
How many cups are required for [tex]3 + \frac{3}{4} = \frac{15}{4}[/tex] batches.
1 batch - (4/3) cups
(15/4) batches - x cups
[tex]x = \frac{4}{3} \times \frac{15}{4} = \frac{60}{12} = 5[/tex]
5 cups of walnuts are needed.
