Answer:
His second smoothie recipe
Explanation:
Given that Victor has two receipts for smoothies:
The first recipe requires 2 strawberries to 7 cups of other ingredients (2:7),
The second recipe requires 3 strawberries to 9 cups of other ingredients, (3:9).
Let's crate a ratio tables in order to determine which recipe has more strawberry compared to other ingredients.
Ratio tables for first Recipe:
Straw berry | Other ingredients
2 | 7
4 | 2(7) = 14
6 | 3(7) = 21
Ratio Table for Second Recipe:
Straw berry | Other ingredients
3 | 9
6 | 2(9) = 18
9 | 3(9) = 27
Comparing his first recipe and his second recipe, when using 6 strawberries, his second recipe requires more cups of strawberry compared to other ingredients (6:18) than that required in his first recipe (6:21).
