Question

A box contains erasers of two

different colors: green and blue.
The ratio of green to blue is 7:5. If
there are 48 total erasers in the
box, how many total green erasers
are there?

Answer 1

There will be 28 green erasers. I know that the ratio is also 28:20, so there are 20 blu erasers.

Explanation:

I time 7 by 4 and 5 by 4 to get the new ratio. I counted the ratios to get to 48.
