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 learn about fractions, use tutorials created by such groups as Khan Academy, GCF LearnFree and Kids Online Resources. Their lessons take students all the way from the most basic information about how fractions work to dividing by fractions, which is one of the more confusing fraction computations.
Full Answer >Fractions are important because people use them everyday in activities like cooking, carpentry, sports, sewing and driving. For example, cooking involves using measurements of ingredients given in fractions, such as 1/2 cup flour, 1/2 teaspoon of sugar or 1/4 teaspoons of salt.
Full Answer >To add or subtract fractions, first determine if the fractions have a common denominator. If the fractions have different denominators, find the least common multiple of the two numbers, and convert the fractions. Once the fractions have similar denominators, add or subtract the numerators to find the answer.
Full Answer >Multiply fractions by multiplying the numerators and then the denominators. The products provide the numerator and denominator of the result, which should then be simplified to the lowest terms.
