Question

A certain shade of pink is created by adding 3 cups of red paint to 7 cups of white paint.

How many cups of red paint should be added to 1 cup of white paint? Do not include units (cups) in your answer.

Type your answer as a fraction or decimal. If you enter a decimal, round to the nearest tenth.

Answer 1

Answer: The answer is 0.429 (0.43 or 0.4)

Step-by-step explanation: When you do 7/3, you get 2.33. So, you take 1 for the 1 cup of red paint and divide it from 2.33 (constant of proportionality) and you get 0.4!
