Dude, all is multiplied by common no. 100 and then find their hcf. Finally, as it was multiplied by 100 so divide the result by 100.

0.9 value is greater than 0.18 and it is a common divisor for 1.08, 0.36 and 0.9.
So, the answer should be 0.9 right?

@Priya.
Just multiply that no's by 100 then find HCF and when you got HCF then again divide the HCF by 100.

The answer is 9 we can divide all these no by 9?
108=9*12
36=4*9
9=1*9
Ans=9 why 18 anyone can explain?

After decimal we are taking the 2 letters from each one thats why we are using 90 in place of 9.

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

@Pratyusha,
108/100=27/25
36/100=9/25
&9/10
hcf of nrs= 9
lcm of drs=50
so ans=9/50=18/100=0.18
108/100=27/25
36/100=9/25
&9/10
hcf of nrs= 9
lcm of drs=50
so ans=9/50=18/100=0.18

Why it can't be 0.9. It is also dividing all of these number so why it cannnot be the solution.

Babu 3, 9, 18, here 18 is the largest number than 3, 9.
So we have to take 18 is the G. C. D.
