2.) forty-three hundredths 43 % = =

3. Decimals  Fraction  Percents
Writing Decimals as Percents
Method 2: (For decimals that have more than two place values)
0.7431
Multiply by 100
• 100
Moves the decimal 2 places to the right.
74.31 = 74.31%

5 •
80%
If the fraction is over 100, that is the percent!

5. Decimals  Fraction  Percents
Writing fractions as percents
Method 2: Use division to write the fraction as a decimal. 3 8
Divide the num. by den.
0.375
• 100 = 37.5
= 37.5%

6. Examples Write each decimal as a percent and a fraction. 0.04
0.04 “four hundredths” %
100
Simplify:
0.04 = 4% = ÷4 ÷4 = 1 25

7. Examples
Write each fraction as a percent and as a decimal. Round the decimal to the nearest hundredths, if necessary. 2 30
To find the decimal and percent…divide!
