Hint:- First we had to simply divide the number by 10x, where x will be the number of digits on the right side of the decimal point and then remove the decimal from numerator to change the given number in fraction form and then to find the percentage of that we simply multiply that by 100.

Complete step-by-step solution -
Let us find the fraction form of the number 0.125.
So, to change the decimal number to fractional number we had to divide the decimal number by 10x, where x is the number of digits after the decimal point and remove the decimal point from the numerator.
So, there are three digits after decimal point in the number 0.125
So, dividing 0.125 by 103 and then removing the decimal point from the numerator. We get the fractional number as 1251000 but we had to reduce this number to the lowest fractional number. So for that we divide the numerator and denominator by common factors.
fraction of 0.125 will be 1251000=25200=540=18
So, the fraction of 0.125 will be 18
To find the percent of 0.125 we had to multiply its fraction by 100.
Percent of 0.125 will be 18×100=1008=504=252=12.5%
So, the percentage of 0.125 is 12.5% and the fraction is 18.
Hence, the correct option will be B.

Note:- Whenever we come up with this type of problem then if we are only asked to find the percent then there is no need to change the fraction to its lowest form because the percent will remain the same. Like the percent of 1251000 and 18 is the same. i.e. 1251000×100=18×100=12.5%. This will be the easiest and efficient way to find the solution of the problem.
