# How Do You Express 12% As A Reduced Common Fraction?

Percentage is most of the time out of 100%. Therefore to turn it into a fraction you put it as 12/100.  To reduce this you have to divide the top and bottom numbers by a common factor (numbers that multiply to make the number, i.e 6 x 2 =12).  The factors of 12 are: 1, 2, 3, 4, 6, 12  The factors of 100 are: 1, 2, 4, 5, 10, 25, 50, 100  The highest possible number which is found in the factors of both is 4.  So 12 / 4 =3  And 100 / 4 =25  Ans = 3/25

A percent is a ratio that compares a number to 100.

12% ------> 12 out of 100 or 12/100.

What is the largest common factor for 12 and 100? 4
12 100
4 x3 4 x 25
4 divided into 12 = 3
4 divided into 100 = 25
12/100= 3/25
