Each marble bag sold by Laura's Marble Company contains 3 red marbles for every 5 blue marbles.
If a bag has 15 red marbles, how many blue marbles does it contain?
well, we know there are 3 red ones for every 5, so how many blue ones are there when there are 15 red ones?

1. 28
2. 88
3. 16
4. 196
Your welcome! :) ❤️
The answer will be 19.5104
I think that it would be easiest to find the area of the whole shape and then subtract the area of the white.
