Acolor called “shocking pink” is made by mixing red paint with white paint. the ratio of red to white is 2 to 7. how much red paint should be mixed with 16 fl. oz of white paint?

To find the amount of red paint to add to the 16 fl oz of white paint, you can set up a proportion and then use cross products to solve for the missing amount of red paint.

red     2     x
white  7 =  16 fl oz

16 x 2 = 7x
32 = 7x
7      7
x = 4 4/7 (approximately 4.6 fl oz)

You will need approximately 4.6 fl oz (or exactly 4 4/7 fl oz) of red paint.
