Exercise 27 Page 23

To write a percent as a fraction, write the number part as a numerator over 100.

3/125

Practice makes perfect
We are asked to write 2 25 % as a fraction in simplest form. To write the percent as a fraction, we can write the number part as a numerator over 100. 2 25 %=2 25/100 Notice that we got a fraction with a numerator that is a mixed number. This means that it is a complex fraction. Recall that complex fractions can be simplified to the form when both the numerator and denominator are integers. Let's start simplifying by writing the complex fraction as a division problem. 2 25/100 = 2 25 Ă· 100Next, we will write the mixed number as an improper fraction.
2 25
2* 5 +2/5
10+2/5
12/5
We found that 2 25 is equal to 125. 2 25 Ă· 100 = 125 Ă· 100 Now we will write the division by 100 as multiplication by the reciprocal of 100, which is 1100. 125 Ă· 100 = 125 * 1100 Let's perform the multiplication to get 2 25 % as a fraction. Then we will reduce the fraction to simplest form.
12/5 * 1/100
12* 1/5* 100
12/500
12Ă· 4/500Ă· 4
3/125
Finally, we got that 2 25 % written as a fraction in simplest form is 3125.
