the ratio of yellow to red balloons is 2:1 respectively. if there are 7 red balloons, how many yellow balloons are there?

7 red balloons means we have twice as many yellow balloons. So 7 * 2 = 14.

Written as a proportion, of yellow to red, we have:
2/1 = y/7 where y is the number of yellow balloons.

Run this proportion through our search engine to get y = 14.
