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:
In percent form, two-thirds is 66.67 percent. To determine this, one divides two by three with a calculator to find 0.66666. To find this fraction in percent form, one has to multiply 0.66666 by 100 to find the answer 66.666 percent, which can be rounded 66.666 to the nearest hundredth to arrive at 66.67 percent.
Full Answer >Percent yield is a chemistry term for the percent of a substance produced in a reaction as compared to how much should have been produced in a complete reaction. A scientific or graphing calculator is needed to balance the terms and then calculate the percentage.
Full Answer >To find the product of fractions, reduce the fractions to the lowest common terms. Multiply the numerators and denominators, and simplify the fraction again to the lowest terms.
Full Answer >Ranking fractions can be done by either converting them to decimals and sorting those values or by converting them to fractions with the least common denominator. If the fractions are improper, then they can be converted into mixed fractions and then they can usually be arranged without any further conversions. After arranging the fractions with the common denominator, they can be switched back to their original form.
