Question

Brown paint can be made by mixing green and red paint in a 3 : 4 ratio. What fraction of the brown paint is green paint? Give your answer in its simplest form.​

Answer 1

3/7

Explanation:

What is a ratio?

A ratio has two or more numbers that symbolize relation to each other. Ratios are used to compare numbers, and you can compare them using division.

Let’s assume that we have 7 units of paint in total. Then, we have 3 units of green paint and 4 units of red paint. When we mix them together, we get 7 units of brown paint.

Because 3 out of the 7 units of paint are green, the fraction of the brown paint that is green paint is
`(3)/(7)`.

Therefore,
`(3)/(7)` of the brown paint is green.
