If the bottom number (denominator) can change to 100 easily, change it.

Example: \( \frac{3}{4} \)

\[ \frac{3}{4} = \frac{3 \times 25}{4 \times 25} = \frac{75}{100} = 75\% \]

Example: \( \frac{7}{20} \)

\[ \frac{7}{20} = \frac{7 \times 5}{20 \times 5} = \frac{35}{100} = 35\% \]

Any fraction can be changed to a percentage by multiplying by \(100\%\).

Example: \( \frac{2}{5} \)

\[ \frac{2}{5} \times 100\% = 40\% \]

Example: \( \frac{6}{25} \)

\[ \frac{6}{25} \times 100\% = 24\% \]

Change to an improper fraction first, then multiply by \(100\%\).

Example: \( 1\frac{1}{2} \)

\[ 1\frac{1}{2} = \frac{3}{2} \qquad \Rightarrow \qquad \frac{3}{2} \times 100\% = 150\% \]

Example: \( 2\frac{1}{4} \)

\[ 2\frac{1}{4} = \frac{9}{4} \qquad \Rightarrow \qquad \frac{9}{4} \times 100\% = 225\% \]

• Percent means “out of 100”.
• If the denominator can easily become 100, use Method 1.
• Otherwise, multiply by \(100\%\).
• Mixed fractions must be turned into improper fractions first.

1. \(\frac{5}{8}\)
2. \(\frac{3}{25}\)
3. \(1\frac{3}{5}\)
4. \(\frac{11}{20}\)
5. \(\frac{7}{2}\)

Convert each to a percentage.
