Rule:

Example: \(0.75\)

\[ 0.75 \times 100\% = 75\% \]

Example: \(0.08\)

\[ 0.08 \times 100\% = 8\% \]

Shortcut: Moving the decimal point 2 places to the right is the same as multiplying by 100.

If the number is greater than 1, the percentage will be more than 100%.

Example: \(1.2\)

\[ 1.2 \times 100\% = 120\% \]

Example: \(2.5\)

\[ 2.5 \times 100\% = 250\% \]

• Multiply by 100 and add the % sign.
• Move the decimal point two places to the right.
• Numbers bigger than 1 become more than 100%.
• Small decimals become small percentages.

1. 0.45
2. 0.09
3. 1.8
4. 0.007
5. 2.36

Convert each decimal into a percentage.
