Is it necessary to write .9 as 90/100 instead of 9/10 to get the right answer?

Yes, we can write 0.9 as 0.90.
Because if we see other given values than after decimal there are two degrees.
Just for making terms we can write 0.9 as 0.90.

1.08-0.36=0.72.
0.90-0.36=0.54.
(0.72-0.54=0.18).
0.90-0.36=0.54.
(0.72-0.54=0.18).

1.08= 27/25, 0.36= 9/25 and 0.9= 9/10.
Now,
The formula of hcf of fraction num is:
HCF of numerator / lcm of denominator,
=> hcf of 27,9,9 is 9 and lcm of 25,25,10 is 50,
=> 9/50 = 0.18.

@ALL.
You have to put the same amount of digits after the decimal point to make the equation equal.

The factors of 9 are: 1, 3, 9.
The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36.
The factors of 108 are: 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108.
Then the greatest common factor is 9. So, the answer should be 0.9.
