Answer: 25/2
Work:
Write 12.5% as the numerator and place 1 in the denominator right below the decimal point followed by the number of zeros required accordingly.
In this case, 12.5 has one number after the decimal, so, we place 10 in the denominator and remove the decimal point. This will make it 125/10, now we can simplify it by dividing the top and bottom by 5.
125/10 = 25/2
