Let's do this the easy way.
1.08 = 108/100 = 27/25,
0.36 = 9/25,
0.9 = 9/10.
Gcd of Fraction = Gcd of Num/LCM of Denominator.
gcd of 27,9,9 = 9,
lcm of 25,25,10 = 50.
9/50 = 0.18.
1.08 = 108/100 = 27/25,
0.36 = 9/25,
0.9 = 9/10.
Gcd of Fraction = Gcd of Num/LCM of Denominator.
gcd of 27,9,9 = 9,
lcm of 25,25,10 = 50.
9/50 = 0.18.

Thanks @Sreeraj for:
3|108, 36, 90
|_____________
3| 36, 12, 30
|_____________
2| 12, 4, 10
|_____________
6, 2, 5
So the H.C.F is 3*3*2 = 18
[need to brush up school's maths book] :P ;)

For those who solved by: 108/100,36/100,9/10 then used the formula (hcf of numerator/lcm of the denominator) and got the answer as 0.09 BUT CAUTION...this formula can only be used when you reduced the terms to lowest form.

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

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.
