4/5 = 8/10.. 
in 8/10 both 8 and 10 are factors of 2.. 2*4=8 and 2*5=10..
so 8/10 can be written as 4/5, hence true

18/6 = 12/4 
18/6=3 and 12/4=3
so this one is true as well..

6/16 = 3/8
6/16 can be written as 3/8, as 2*3=6 and 2*8=16
so this one is true too.

27/9 = 22/4
here, 27/9=3 and 22/4=11/2
so this one isnt true..
