Answer:
21 cups oil
14 cups soy sauce
7 cups orange juice
Explanation:
Use 1 cup for 1 part. The original recipe as given with its small amounts would make a total of 3 + 2 + 1 = 6 parts, or 6 cups of sauce.
You want to make 42 cups.
42/6 = 7
The amount you want to make is 7 times the amounts in the ratio.
3 parts oil: 3 × 7 = 21: 21 cups oil
2 parts soy sauce: 2 × 7 = 14: 14 cups soy sauce
1 part orange juice: 1 × 7 = 7: 7 cups orange juice
Check: 21 + 14 + 7 = 42
The amounts above do make 42 cups in total.
Answer:
21 cups oil
14 cups soy sauce
7 cups orange juice
