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.
Know MoreBenchmark 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:
To divide fractions, you must find the reciprocal of the divisor. Multiply the dividend and the reciprocal of the divisor, and simplify the result if possible.
Full Answer >Fractions first appeared in the works of Egyptian mathematicians in the form of unit fractions, unlike the ratios used today. They did not enter Europe until the 17th century.
Full Answer >Equivalent fractions are fractions that have the same numerical value. For example, 1/2 and 2/4 are equivalent fractions, as they are both equal to 0.5.
Full Answer >Add and subtract fractions by finding like denominators and then adding or subtracting the numerators. To multiply fractions, simply multiply the numerators and denominators together. To divide fractions, multiply the first fraction by the inverse of the second fraction. Finish by simplifying your answer.
