A 720 ml container holds a mixture of red yellow and white paint in 5 3 12 ratio How much more red paint than yellow is present it the mixture?

First I would add the total number of parts together.

5 + 3 + 12 = 20

Now we know that red is 5/20th of the entire mixture, yellow is 3/20th, and white is 12/20th.

red = 5/20 * 720 ml = 180 ml

yellow = 3/20 * 720 ml = 108 ml

white = 12/20 * 720 = 432 ml

We can double check by adding them up and it should come out to 720 ml.

180 ml + 108 ml + 432 ml = 720 ml

180 ml - 108 ml = 72 ml

There is 72 ml more red paint then yellow paint.
