Converting between fractions and percentages

## Converting from a fraction to a percentage

1. Divide the numerator by the denominator to get a decimal number.
• Example: $$\dfrac {3}{4} = 3\: \text{divided by}\: 4 = 0.75$$
2. Multiply by 100. This moves the decimal place to the right two places.
• Example: $$0.75 \times 100 = 75$$
3. Put a % symbol at the end.
• Example: $$75 → 75\%$$
• Final Answer: $$\dfrac {3}{4} = 75\%$$

## Converting from a percentage to a fraction

1. Remove the % symbol from the number and divide by 100.
• Example: $$40\% → \dfrac {40}{100}$$
2. Simplify the fraction.
• Example: $$\displaystyle 40/100 =\frac {40}{100}=\frac {20⋅2} {20⋅5}= \frac {2}{5}$$
3. Final answer: $$40\% = \dfrac {2}{5}$$

### Practice Problems

1. Convert $$22\%$$ to a fraction. Simplify the fraction as much as possible. (
Solution
Solution:
$$\displaystyle \frac{22}{100}=\frac{11}{50}$$
)
2. Convert $$5\%$$ to a fraction. Simplify the fraction as much as possible. (
Solution
Solution:
$$\dfrac{1}{20}$$
Details:
$$\dfrac{5}{100}$$

Simplify the fraction as much as possible.

$$\displaystyle \frac{5}{100}=\frac{5\cdot1}{5\cdot20}=\frac{1}{20}$$
)
3. Convert $$250\%$$ to a fraction. Simplify as much as possible. Convert to a mixed fraction if needed. (
Solution
Solution:
$$\displaystyle \frac{250}{100}=\frac{5\cdot50}{2\cdot50}=\frac{5}{2}=2\frac{1}{2}$$
)
4. Convert $$\dfrac{3}{5}$$ to a percentage. (
Solution
Solution:
$$60\%$$
Details:
$$\displaystyle \frac{3}{5} = 0.6$$
$$0.6 \times 100$$ with a % symbol = $$60\%$$
)
5. Convert $$\dfrac{5}{8}$$ to a percentage. (
Solution
Solution:
$$62.5\%$$
Details:
$$\displaystyle \frac{5}{8} = 0.625$$
$$0.625 \times 100$$ with a % symbol = $$62.5\%$$
)
6. Convert $$\dfrac{15}{8}$$ to a percentage. (
Solution
Solution:
$$187.5\%$$
Details:
$$\displaystyle \frac{15}{8} = 1.875$$
$$1.875 \times 100$$ with a % symbol = $$187.5%$$
