Question

What is the least number of drops of red, blue, and yellow pigment that Ava

can add to a gallon of white paint so that the custom color consists of 25%
red, 35% blue, and 40% yellow pigment?

Answer 1

5 red, 7 blue and 8 yellow

Explanation:

Just make a ratio and simplify

Red : Blue : Yellow

25 : 35 : 40

All divisible by 5

5 : 7 : 8

These dont have a common factor so this is the simplest ratio

Therefore the minimum drops Ava can add to a gallon of white paint to have that ratio are 5 red drops, 7 blue drops and 8 yellow drops.
