Exercise 34 Page 24

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

257/800

Practice makes perfect
We are asked to write 32 18 % as a fraction in simplest form. To write the percent as a fraction, we can write the number part as a numerator over 100. 32 18 %=32 18/100 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. 32 18/100 = 32 18 Ă· 100Next, we will write the mixed number as an improper fraction.
32 18
32* 8 +1/8
256+1/8
257/8
We found that 32 18 is equal to 2578. 32 18 Ă· 100 = 2578 Ă· 100 Now we will write the division by 100 as multiplication by the reciprocal of 100, which is 1100. 2578 Ă· 100 = 2578 * 1100 Let's perform the multiplication to get 32 18 % as a fraction.
257/8 * 1/100
257* 1/8* 100
257/800
Finally, we got that 32 18 % written as a fraction in simplest form is 257800.
