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!

10:8 and 15:12

Step-by-step 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

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
