=
( cross- multiply )
5x = 84 ( divide both sides by 5 )
x = 16.8
This is the steps how i solved it.

Answer: 9:5
Step-by-step explanation:
81:45 I first just divided them both by three and got 27:15 then they were both divisible by 3 so then I got 9:5
(2/3)x = 10
(3/2)(2/3)x = 10(3/2)
x = 30/2 = 15
