Answer 11

This is the same thing except for the fact that you just had to add three to twenty (that we got before), which makes us get 20. If we subtract 8 from 20, we get 12. We can now put it as a ratio of amount not pink to the total amount of marbles -> 12/20. What is the simplified fraction of 12/20?

Answer 12

3/5
