Sir, I really don't understand that how can we pick .0.2 common from only one denominator when there's another denominator as 0.04.

Just simply take 2^3 as common in the denominator.
(0.1)^3 + (0.02)^3/2^3(0.1^3+0.02^3),
= 1/2^3 = 1/8,
= 0.125.
(0.1)^3 + (0.02)^3/2^3(0.1^3+0.02^3),
= 1/2^3 = 1/8,
= 0.125.

1*1*1* + 2*2*2 / 2*2*2 + 4*4*4,
1+8 / 8+64 = 9/72.
1/8 = 0.125.
1+8 / 8+64 = 9/72.
1/8 = 0.125.
