Answer: I believe your answers are bottom middle 2:1/2 and bottom right 2 1/2:5/8.
Top left may be correct, but the ratio is 1:4, so I don't think it is one of the answers you are looking for.
Step-by-step explanation: To solve this, you need to have a ratio of 4:1. In order to find these you need to make sure some of the fractions have the same denominator. I can explain more if you need me to.
