Question

How can I do this? I am not asking for answers, but for the way to do it. I’m struggling, and It would mean so much! Thanks!

Answer 1

10:8 and 15:12

Explanation:

you could think of a ratio as a multiple, where the other ratios will alway be able to go to the other ones. Like 10:8 is a ratio of 5:4 because 10:8 can be both divided by 2 to get 5:4

Answer 2

top row: 10, 15
bottom row 8, 12
hope this helps
