Answer:

#3/2#

Explanation:

Write as #x/(1.2)#

For #x=1.8" we have "1.8/1.2#

To make the maths easier apply the principle of ratios in that

#1.8/1.2" "=" "(1.8xx10)/(1.2xx10)" "=" "18/12#

In effect you are multiplying by 1 but in the form of #1=10/10#
Anything multiplied by 1 does not change its intrinsic value.

But #18/12 = (18-:6)/(12-:6) = 3/2#
