**A list of benchmark fractions include 1/4, 1/3, 1/2, 2/3 and 3/4.** Benchmark fractions are common fractions that are used for comparison to other numbers. For example, the benchmark fraction 1/10 is often used because of how it relates to decimals.

Benchmark fractions are useful to know because of how they relate to common percentages and decimals. Every fraction can be converted into a decimal by dividing the denominator, or the bottom number, into the numerator, the top number. The decimal can then be converted into a percentage by multiplying by 100. A list of some benchmark fractions and their equivalents are:

- 1/2 = 50 percent = 0.5
- 1/4 = 25 percent = 0.25
- 2/5 = 40 percent = 0.4
- 3/8 = 37.5 percent = 0.375
- 7/10 = 70 percent = 0.7
- 1/9 = 11.11 percent = 0.111
- 1/8 = 12.5 percent = 0.125
- 4/5 = 80 percent = 0.8
