Aptitude - Decimal Fraction - Discussion

Hey everyone.

Someone is confused about how we get to the place of.

(0.1667), (0.8333), (0.2222), (0.6667), (0.1250) we get 1/6, 5, 6, 2/3, 125/100.

Let me explain;

Here; They ask approx value so we consider 0. 1667 as 0. 1666 and by converting it into a fraction we get 1/6.

Calculation part;

0.1666 as 0. 16 where 6 has a bar on it.
0.16. = 16/90 = 1/6.

Similarly, 0. 8333 consider 0. 83 and 3 has a bar on it.

Calculation part ;

0.83. = 83 - 8 /90 = 75/90 = 5/6.

Similarly, consider 0. 6667 as 0. 6666 solving it we get 2/3.

Calculation part;

0.6. = 6/9 = 2/3.

Hear 0.1250 as 0.124 solving it we get 125/100.

How the simplification is done?

I'm not able to understand. Please explain this in detail.

I didn't understand the concept behind 0.1250 =125/1000.

Anyone, please explain
