Question

if there are 15 red ball 20 blue ball find ratio of red balloons to total number of balloons

Answer 1

Step-by-step explanation:

Using the ratio 3:5, you are dealing with a number of groups of 8, since 3 + 5 = 8. The first step is to determine how many groups of 8 are involved. To find this divide the total number of balloons (40) by 8.

40/8 = 5, so there are 5 groups of eight balloons.

3 balloons in each group of 8 are red. Multiply 3 (red balloons in each group) by 5 ( the number of groups).

3 x 5 = 15 red balloons

5 x 5 = 25 blue balloons

25 + 15 = 40 balloons total

Answer 2

Answer:

red balloons yellow balloons
