Question

54:18 and 18:6 ratio

Answer 1

I pretty sure it's, for problem one, 54/18, and the other way is 54 to 18. You already did the last way, which is 54:18. Do the same thing in the second problem. 

Answer 2

well 54 divided evenly with 27 and 18 divides evenly with the number 9 so 27/9    and 18 >>>>>9   and 6 >>>>3    so 27/9 and 9/ 3  Hope this helps :)
