Question

The ratio of red balloons and blue balloons is 5:7. If there are 360
balloons in all, find the number of red balloons and blue balloons.

Answer 1

Answer:

blue balloons = 210

red balloons = 150

Step-by-step explanation:

let the share between the ratios be x

now we know that 5x + 7x = 360

therefore 12x = 360

x = 360/12

x = 30

now the number of red balloons =

5 x 30

= 150

number of blue balloons =

7 x 30

= 210
