I didn't understand this question?
Find the lcm of 3, 2. 7, 0.09? I need a full explanation of the solution. Can anyone explain me?

But how become HCF 2*3*3 = 18?
Please explain me briefly?

Greatest common divisor has to be smaller than the numbers which are divided by G.C.D. And it has to be greatest, hasn't it?
So here 0.18 is greater than 0.09. So answer is 0.18.
So here 0.18 is greater than 0.09. So answer is 0.18.

Answer should be 0.09 as you can't change format of number while doing fraction G.C.D.

0.18 is correct answer.
In these path hcf = hcf (numerator)/lcm(denominator).
So we can write 1.08, 0.36, and 0.90 as 108/100 and 36/100 and 90/100 hsf (108, 36, 90) = 18 AND lcm (100, 100, 100) = 100.
As for formula 18/100 = 0.18.
So the answer is 0.18.

@Shiv,
Because 0.9 = 0.90 (9/10 = 90/100) if you divided to 90/100 by 10 then you'll get 9/10. 1/2 = 0.5 = 0.50 (these all numbers are called "Half").
So we can use 90/100 in place of 9/10.

1.08*100 = 108.
0.36*100 = 36.
0.9*100 = 90.
@Shiv I hope this will help you out :).
0.36*100 = 36.
0.9*100 = 90.
@Shiv I hope this will help you out :).
