Purple paint is made with a 16:3:1 ratio of white paint:blue paint:red paint. How much white paint, in gallons, is needed in order to make one gallon of purple paint? Express your answer as a common fraction.

Respuesta :

4/5 gallons. assuming 16:3:1 are gallons you have 20 gallons. you can make a proportion 16/20 = x/1. resolving: 20x = 16. x = 16/20. simplify dividing by 4 it is equal to 4/5 gallons.

Answer:

4/5

Step-by-step explanation:

The purple paint is split into 16+3+1=20 parts: 16 parts of white, 3 parts of blue, and 1 part of red. Thus, in one gallon of purple paint, 16 out of the total 20 parts are white paint, so there are 16/20 x 1 gallon = 4/5 gallons of white paint in one gallon of purple paint.
