Question

Stephen uses \dfrac{2}{25} 25 2 ​ kilograms of tofu in each serving of his famous tofu dish. He has 1\dfrac{1}{10}1 10 1 ​ kilograms of tofu. How many servings can Stephen make?

Answer 1

13 3/4 servings

Explanation:

Stephen has 1 1/10 kg of tofu.

He uses 2/25 kg in each serving.

We will divide to figure out how many servings he can make

1 1/10 ÷ 2/25

We need to change the mixed number 1 1/10 to an improper fraction

1 1/10 = (10*1 + 1) /10 = 11/10

11/10 ÷2/25

Copy dot flip

11/10 * 25/2

275/20

Divide the top and bottom by 5

55/4

We will change this back into an improper fraction

4 goes into 55 13 times with 3 left over

13 3/4

He can make 13 3/4 servings
