Answer:
Step-by-step explanation:
Well we know that the decimal point was moved two places to the right to have a percentage.
So the starting decimal was .125 which is 125/1000. We can reduce this by dividing the numerator and denominator by 25, which gives us 5/40 and this can be reduced to 1/8.
12.5% is 1/8 as a fraction.
You could have converted 12.5% to a fraction in another way. Percent means one hundred. So 12.5% could be 12 and 5/10 /100.
12 and 5/10 = 125/10 divided by 100. Invert 100/1 to 1/100. Then multiply.
125/10 X 1/100 = 125/1000 which can be reduced by dividing numerator and denominator by 125.
125/1000 = 1/8
The first way seemed easier for me.
