Percentages are essentially fractions with a denominator of 100. However, expressing them in their simplest fractional form can:
- Make calculations easier, especially when dealing with complex numbers.
- Provide a clearer understanding of the proportion being represented.
- Simplify comparisons between different quantities.
How to Write a Percent as a Fraction in Simplest Form
The process involves a few straightforward steps:
- Write the percent as a fraction with a denominator of 100: For example, 25% becomes 25/100.
- Simplify the fraction: Find the greatest common factor (GCF) of the numerator and denominator and divide both by it.
Examples
Example 1: Convert 40% to a fraction in simplest form.
- 40% = 40/100
- The GCF of 40 and 100 is 20. Dividing both by 20, we get 2/5.
Therefore, 40% is equal to 2/5 in simplest form.
Example 2: Convert 75% to a fraction in simplest form.
- 75% = 75/100
- The GCF of 75 and 100 is 25. Dividing both by 25, we get 3/4.
Therefore, 75% is equal to 3/4 in simplest form.
Example 3: Convert 12.5% to a fraction in simplest form.
- 12.5% = 12.5/100
- To remove the decimal, multiply both numerator and denominator by 10: 125/1000
- The GCF of 125 and 1000 is 125. Dividing both by 125, we get 1/8.
Therefore, 12.5% is equal to 1/8 in simplest form.
