What Is a List of Some Benchmark Fractions?

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
