Multiplying both sides by 10 would cancel the fraction on the right hand side. That leaves your answer, as a top heavy fraction.

Oh well just cross multiply and then solve

You should get "n", is that right? if this is the case why you don't change this equation to "n"? its simple:

10/8 = n/10 | * 10
100/8 = n
12,5 = n

And now you can check your solution:

10/8 = 12,5/10
1,25 = 1,25

as you can see that it is the right solution.
