To convert decimals to percentages multiply the decimal by 100

Example 1

Change the following to percentage form

a. 0.25

b. 1.5

c. 0.007

Solution

a. \(\scriptsize 0.25 \\ = \scriptsize 0.25 \: \times \: 100 \% \\ = \frac {25}{100} \scriptsize \: \times \: 100\% \\ \scriptsize = 25 \%\)

b. \( \scriptsize 1.5 \\ = \scriptsize 1.5 \: \times \: 100 \% \\ = \frac {15}{10} \scriptsize \: \times \: 100\% \\ \scriptsize = 150 \%\)

c. \(\scriptsize 0.007 \\ = \scriptsize 0.007 \: \times \: 100 \% \\ = \frac {7}{1000} \scriptsize \: \times \: 100\% \\ = \frac {7}{10} \\ = \scriptsize 0.7 \%\)
