Answer 1

Explanation:

Convert both sides of the : in the same unit and simplify as much as possible

Example:

80c : $8

Convert dollars into cents

80c : 800c

Divide both sides by 80

1 : 10

Answer 2

As it says in the hint at the top of the picture, you need to convert each of them to the same units first. So say for a, you’d either turn 80c into dollars, or you’d turn $8 into cents, and then from there on you just simplify them. I hope that helps :)
