Question

the ratio of yellow, blue and red ballons is 2:3:2 respectivley. if the total number of ballons is 28, how many yellow ballons are there

Answer 1

To determine the number of yellow balloons, we need to calculate the fraction of yellow balloons out of the total number of balloons.

The given ratio of yellow, blue, and red balloons is 2:3:2.

To find the number of yellow balloons, we first need to determine the total number of parts in the ratio:

2 + 3 + 2 = 7

Next, we divide the total number of balloons by the total number of parts to find the value of each part:

28 / 7 = 4

Finally, to find the number of yellow balloons, we multiply the value of each part by the number of parts for yellow balloons:

2 * 4 = 8

Therefore, there are 8 yellow balloons.

Answer 2

8 yellow balloons.

Explanation:

In the ratio,
`(2)/(7)` of balloons are yellow because the numbers in the ratio add up to 7.
`(2)/(7)*28=8` which is the ratio of yellow balloons to all balloons times the total number of balloons, which is 8. Hope this helps!
