Question

A florist sells holiday bouquets that use roses and carnations in a ratio of 2:7. She receives a shipment of 343 carnations. How many roses will the florist need?

Answer 1

98

Explanation:

Roses and carnations will always be at a ratio of 2:7. And 7 represents the carnations. If there are 343 carnations in an order, divide that by 7. You get 49, which is how many times the original 7 was repeated to get to 343. And since the ratio will always be the same, you multiply the same number by the number of roses. So 49*2 is 98.
