Question

A chef uses 1/2 cup of cheese for a small pizza. There are 6 grams of fat in 1/4 cup of cheese. Drag one expression next to each question. The correct expression for each row is a way to answer that question.

How many grams of fat are in 1/2 cup of cheese?
How many cups of cheese will the chef need to make 13 small pizzas?
How many small pizzas could the chef make if he has 3/4 of cheese?

Answer 1

12 grams; 26 cups; 1.5 pizzas

Explanation:

There are 6 grams of fat in 1/4 cup of cheese. To find the number of grams in 1/2 cup of cheese, we would multiply by 2. This is because 1/2 = 2/4 = 1/4(2). This makes the number of grams 6(2) = 12 grams.

It takes 1/2 cup of cheese for one small pizza. To find the number of cups of cheese needed to make 13 small pizzas, we divide:

13÷1/2 = 13/1 ÷ 1/2

To divide fractions, multiply by the reciprocal (flip the second one and multiply):

13/1 × 2/1 = 26/1 = 26

He needs 26 cups to make 13 small pizzas.

If he only has 3/4 of a cup of cheese, he can make

3/4 ÷ 1/2 = 3/4 × 2/1 = 6/4 = 1.5 pizzas.

Answer 2

12 grams of fat in 1/2 cup of cheese

6 1/2 cups of cheese for 13 pizzas

1 because 1/4 +1/4 =1/2 you would have 1/4 left
