Question

a painter mixes 2.5 pints of yellow paint with 4 pints of red paint to make a certain shade of orange paint. How many pints of yellow paint should be mixed with 10 pints of red paint to make this shade of orange?

Answer 1

2.5 * 10/4 = 6.25 pints of yellow paint

Answer 2

6 1/4 pints

Explanation:

The ratio of yellow paint to red paint = 2.5 : 4.

We have 10 pints of red paint so 2.5 / 4 = x / 10 where x is the volume of yellow paint.

4x = 2.5 * 10

x = 25/4

= 6 1/4 pints.
