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.

it's basically a bar concept. That is 0.22222 can be written as 0.2 and infraction it can be written as 2/9.

The formula is (number without decimal - non-repeating numbers)/put 9's the number of repeating numbers and 0's the number of non-repeating numbers.

Suppose, 0.35232323 it can be written as (3523 - 35)/(9900).
Put that in that problem and you are good to go.

Hi all, from my understanding, the conversion to a fraction is actually used for non-terminating recurring decimals, however, that is not the case here, all are terminating decimals, we can convert them only like, 0.67 = 67/100.

For getting 0.16667 as 1/6, we can do:

0.1667*10 = 1.6667.

Now, 1.6667 is equal to 1+ 0.6667, we know how to convert 0.6667 to a fraction.
0.6667 = 6/9 => 2/3.

Therefore, we have 1+ 0.667 => 1+(2/3)=> 5/3,

But remember we multiplied by 10 in the beginning, so we divide by 10 to nullify the change.
Therefore (5/3)/10 => 1/6.
