Question

Jamal needs three gallons of a mix that is two parts blue paint, three parts white paint and one part red paint. How many gallons of red paint will he need?

Answer 1

He will need 1/2(half) gallon of red paint

Answer 2

`(1)/(2)` gallon

Explanation:

The mix is
`$(2)/(2+3+1)=\frac13$` blue paint,
`$\frac12$` white paint, and
`$\frac16$` red paint. He therefore needs
`$\frac36=\boxed{\frac12}$` gallons of red paint.

Hope this helped! :)
