Equivalent fractions can be found by either dividing or multiplying both the numerator and denominator by the same nonzero number. For example, when the top, or numerator, and bottom, or denominator, of the fraction 2/4 is divided by 2, the result is the equivalent fraction 1/2. When the top and bottom of 2/4 is multiplied by 2, the equivalent fraction is 4/8.
Know MoreEquivalent fractions are fractions that represent the same value, although the numbers in the fraction are different. When a fraction can no longer be divided by a whole number, the fraction has been reduced to its simplest form, or simplified. For example, 1/2 can no longer be divided by a whole number. Other equivalent fractions of 2/4 are 6/12, 8/16 and 10/20. Equivalent fractions can only be found by multiplying or dividing, not by adding or subtracting.
Other types of fractions include proper, improper, reciprocal and mixed number. Proper fractions are fractions when the numerator is a smaller number than the denominator. Examples of proper fractions include 1/2, 4/5 and 5/25. Improper fractions are fractions that have a smaller denominator than numerator. Examples of these include 9/1, 8/3 and 6/4. Fractions that have an equal numerator and denominator, such as 10/10, are also improper fractions. Reciprocal fractions are fractions that when multiplied, equal 1. For example, 4/3 and 3/4 are reciprocals because 3/4*4/3 is equal to 12/12, or 1. Mixed numbers are comprised of a whole number, such as 6, and a proper fraction, such as 1/5, which together are written as 6 1/5.

Full Answer >To simplify a complex fraction, calculate common denominators for both the numerator and the denominator, combine like terms, and then solve the complex fraction by flipping the denominator to multiply. Dividing and multiplying are inverse operations, so flipping is the easiest way to solve.
Full Answer >To solve complex fractions, begin by resolving the numerator (top term) and denominator (bottom term) into one fraction each, flip the bottom fraction and multiply across. Simplify where possible to arrive at the final answer.
Full Answer >Improper fractions are those in which the numerator (top number) is larger than the denominator (bottom number). According to Math is Fun, improper fractions are better for use in mathematical formulae, but mixed fractions are better for understanding and spoken language. When dealing with formulae or math operations, wait until you have made all the other manipulations before converting a fraction to a mixed number for your final answer.
