Hello

3 + 5 + 7 = 15

cups of tomato =  105 x 5/15 = 35

Answer:

49

Step-by-step explanation:

sum the parts of the ratio, 3 + 5 + 7 = 15 parts

divide cups of salsa by 15 to find value of one part of the ratio

105 ÷ 15 = 7 ← value of 1 part of the ratio , then

7 parts = 7 × 7 = 49

49 cups of tomato are required
