Answer:
98
Step-by-step 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.
