Question

Paint is to be mixed so that the ratio of red paint to white paint is 3 to 2. If Ben wants to make 30 cans of the mixture and all cans hold the same volume of paint, how many cans of red paint will he need?

Accepted Answer

Since 3/(3+2)=3/5 of the total amount of paint is red, he will need 3530=18 cans of red paint.
