Answer:

65 blue balloons

Step-by-step explanation:

The ratio of green balloons to blue balloons to red balloons at a school party was 2:5:4. Then, every 2 + 5 + 4 = 11 balloons, 5 are blue. The ratio of blue balloons to total balloons is 5:11. The number of blue balloons in 143 total balloons is:

143 total balloons × (5 blue balloons/11 total balloons) = 65 blue balloons
