#18/25#

0.72 is the same as #72/100# (try putting both into a calculator!) as you can view 1.00 as #1/1#.

Reducing the fraction gives you #72/100#= #18/25#.

Below...

You could do this two ways:

#0.72 -> 72/100 -> 18/25#

when dividing the numerator and denominator by #4#.

Or alternatively...

let #x =0.72#

#10x=7.2#

#100x=72#

#1000x=720#

#1000x-100x=720-72 -> 900x=648 -> x=648/900 -> 18/25#

when dividing the numerator and denominator by #36#
