Jess is painting his car. He’s created a purple color that uses red paint and blue paint in a ratio of 6:5. Jess uses 15 pints of blue paint. How many pints of paint does he use in total?

Since the ratio of red to blue paint is 6 and 5. And 15 pints are blue you do 15 divided by 5 and it is 3. So you would do the same for red and it will be 18 so you do 18 plus 15 which is 33 pints in total
