Percents and Fractions

Vocabulary A percent is a ratio that compares a number to 100. It means “per 100.” 49 out of 100 is 49%.

Writing Percents as Fractions Place the percent in a fraction with a denominator of 100. Simplify the fraction. 26% %

Writing Fractions as Percents Write a proportion with a denominator of 100 if possible (easiest way). Then write as a percent. OR Divide the numerator by the denominator to get a decimal. Then change the decimal to a percent by moving the decimal point to the right (multiply by 100) ? 24% 100
