Question

In a shopping bag of grapes and pineapple slices, the ratio of grapes to pineapple slices is 7:3. If the bag contains 120 grapes, how many pineapple slices are there

Answer 1

280 Pineapple Slices

Explanation:

To set this up, we put the fraction 7/3 next to our assumed fraction, x/120. X being the number of pineapple slices in the shopping bag. Then, we multiply 7 x 120 (840) and divide that by 3. Our answer comes out to 280, which we can prove by seeing that 3 x 4 = 120 and 7 x 4 = 280. This is also a similar way to solve the problem.
