It is very simple yar.
3/2 = 1.5
Using vulgar-fraction instead of decimal-value of the given numbers will be helpful for solving problems.

1.5 = 15/10 > Dividing both by 5 we get 3/2.

1.5 is the same as 1+0.5.
Now 0.5 = 1/2. Now 1+1/2 = 3/2.
I hope this is now clearer.

Hi guys please let me know if this method is right:
(0.04)^-1.5 = (4/100)^-1.5
=> (2^2/10^2)^-(3/2)
=> (2/10)^-3 = 1/125
=> 125
(0.04)^-1.5 = (4/100)^-1.5
=> (2^2/10^2)^-(3/2)
=> (2/10)^-3 = 1/125
=> 125
