Question

9:12=15:______

I need the answer pls!

Answer 1

15:20

Explanation:

We can simplify the ratio to 3:4

after doing that we can multiply both sides by 5 giving us

15:20 as our answer

Or you can cross multiply

9 : 12 = 15 : x

Now we have 9x = 180

divide both sides by 9 and we get

x=20

which would work giving us the ratio of 9 : 12 = 15 : 20
