Answer:
13 3/4 servings
Step-by-step 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
