How do you change 0.72 into a fraction?

Answer 1

Genesis Allen

#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...

Alternatively, though...

Let #x = 0.72#.

#10x= 7.2#

#100x=72#

#1000x=720#

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

when #36# is applied to the numerator and denominator
