#5 : 2#

One of the rules of ratios is that there should be no fractions, only whole numbers.

We have # 1/2 : 1/5#

One method is to change them to a common denominator.

However, let's multiply by that LCM instead, because this will allow us to cancel the denominators altogether immediat.ely

#10/1 xx 1/2 : 1/5 xx 10/1

#cancel10^5/1 xx 1/cancel2 : 1/cancel5 xx cancel10^2/1#

#5 : 2#
