Answer:
6a:10b
Step-by-step explanation:
Make both C's equal eachother which we could make 12
4x3=12 and 6x2=12
so we will have to do the same for the other numbers so when 4x3=12 then 2x3=6 and then do the same for 5b where 6x2=12 and 5x2=10
this would make the ratio 6a:12c:10b which would then make the ratio 6a:10b
