Answer 1

You can set up a ratio here

Answer 2

3 roses
---------
4 tulips
Now think what would you multiply by to get 15 roses to go from the ratio to option A?

Answer 3

4/5

Answer 4

Think of just the roses for now if you have 3 roses in the beginning what do you multiply by to get 15 so like this...3x=15 so almost like how many groups of roses would need need if you have 3 roses in each group to be 15 all together

Answer 5

5

Answer 6

Good now if you do that to the top you need to do that to the bottom so if you have 4 tuplips and 5 groups of them how many will you have all together?
