To make a certain shade of orange, you need to mix 12 cups of yellow with 8 cups of red.
If you want to make 80 cups of paint, how many cups of yellow would you need?
To make the shade you want, it takes 12 cups of yellow and 8 cups of red.
In other words, you used a total of 20 cups of paint to get the shade right.
To end up with 80 cups of paint, you just need to do the same thing 4 times.
So 4 times 12 cups of yellow is 48 cups of yellow.
And, of course, 4 times 8 cups of red is 32 cups of red. 48 + 32 = 80 the amount you want.
