Question

There are 100 balloons in total the ratio between the yellow and blue balloons is 8 to 12 how many are yellow

Answer 1

Answer:

The ratio of yellow balloons to blue balloons is 8:12

Then there are 100 balloons. Making the equation, we are able to have:

8X + 12X = 1000

20x = 1000

X = 50.

Yellow balloons = 8x = 8 * 50 = 400 yellow balloons

Blue balloons = 12X = 12 * 50 = 600 blue balloons

So there are  400 yellows balloons.

Answer 2

If you have 8 yellow balloons for every 12 blue balloons, then if you have 20 balloons in total, 8 out of 20 of those balloons will be yellow. Then you can set up this ratio.

Then, you can use either cross multiplication or multiply the numerator and denominator by the same number to help solve for x. Personally, I prefer cross multiplication.

Finally, solve for x and if you had 100 balloons, you will have 40 yellow balloons.
