Question

Roger makes 70 gallons of pink paint by mixing red and white paint. He uses 21 gallons of red and 49 white. What percent of pink paint is made of red paint

Answer 1

30%

Explanation:

In this case, we do not need to regard the amount of white paint. That information is just to confuse you.

The amount of red paint in the pink paint mixture can be represented by the fraction 21/70. All you have to do is simplify that to get 0.3, which is also represented as 30%. hope this helps :)
