Question

Hugo is making blue paint with red paint to creat purple paint. The ratio of blue to red is 3 to 2. How many pints of blue paint will he use to create 40 pints of purple paint

Answer 1

3 parts blue and 2 parts red equals 5 parts. 40 pints divided by 5 parts equals 8. So 3 parts blue x 8 =24 parts blue. 2 parts red is 16 and 24 plus 16 does equal 40
