This is arguably the simplest way to ensure that the fractions have a common denominator. The numerators also need to be multiplied by the appropriate factors to preserve the value of the fraction as a whole. Multiplying all of the denominators ensures that the new denominator is certain to be a multiple of each individual denominator. One method for finding a common denominator involves multiplying the numerators and denominators of all of the fractions involved by the product of the denominators of each fraction. Unlike adding and subtracting integers such as 2 and 8, fractions require a common denominator to undergo these operations. Fractions can undergo many different operations, some of which are mentioned below. Note that the denominator of a fraction cannot be 0, as it would make the fraction undefined. If a person were to eat 3 slices, the remaining fraction of the pie would therefore be 5Īs shown in the image to the right. 1 of those 8 slices would constitute the numerator of a fraction, while the total of 8 slices that comprises the whole pie would be the denominator. A more illustrative example could involve a pie with 8 slices. , the numerator is 3, and the denominator is 8. The numerator represents the number of equal parts of a whole, while the denominator is the total number of parts that make up said whole. It consists of a numerator and a denominator. In mathematics, a fraction is a number that represents a part of a whole. Use this calculator if the numerators or denominators are very big integers. Fields above the solid black line represent the numerator, while fields below represent the denominator. When the equivalent fraction cannot be calculated, the error "Sorry, overflow error" will be displayed.Home / math / fraction calculator Fraction Calculatorīelow are multiple fraction calculators capable of addition, subtraction, multiplication, division, simplification, and conversion between fractions and decimals. Very big numbers or numbers with many digits after the floating point may not be converted here. The result of the conversion is therefore (5/2)+(1/30)=38/15Īll fractions are reduced as soon as possible to simplify the subsequent operations. Each element is converted separately, the non repeating portion is converted as explained above, while the fraction for the repeating portion is obtained by dividing the repeating figures by a number of 9's equal to the length of the sequence, followed by a number of '0's equal to the the number of 0's between the dot and the repeating digits.įor example the number 2.5333. When the number has infinitely repeating decimals, then the fraction is obtained by breaking the number into a sum of the non-repeating portion and the repeating portion. The resulting number is then shown divided by the same power of 10 to represent the original number as a fraction. This is because the number is multiplied by a power of 10 such that the decimal point is removed. When the number has no repeating decimal portion, the numerator of the equivalent fraction is obtained by removing the dot from the number, and the denominator is '1' followed by the same number of 0's as the length of the decimal portion.įor example the number 12.4 is equal to 124 divided by 10, so the equivalent fraction is 124/10, which, when simplified, becomes 62/5.

How to convert a decimal number to it's equivalent fraction See the following table for examples: Type of number You may also convert to fractions numbers with infinitely repeating digits by enclosing the repeating digits in parenthesis or by adding '.' at the end of the number.
You may enter simple rational numbers with the whole portion separated from the decimal portion by a decimal point (ex.
