All are multiplied by 10000 so that they can become whole numbers.
Take the first two digits 16*83*33=43824.
Take denominator first two digits 22*66*12=17424.
So, 43824/17424 = 2.51.

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.
0.1667*10 = 1.6667.
Now, 1.6667 is equal to 1+ 0.6667, we know how to convert 0.6667 to a fraction.

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.

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.
