A salsa recipe uses green pepper, onion, and tomato in the extended ratio 1:3:9. How many cups of tomato are needed to make 117 cups of salsa? (1 point) Responses 27 cups of tomato 27 cups of tomato 9 cups of tomato 9 cups of tomato 81 cups of tomato 81 cups of tomato 90 cups of tomato
The total number of parts in the extended ratio is 1 + 3 + 9 = 13 parts.
To make 117 cups of salsa, each part is equal to 117/13 = <<117/13=9>>9 cups.
Therefore, the number of cups of tomato needed is 9 * 9 = <<9*9=81>>81 cups of tomato. Answer: \boxed{81}.
