Fractions represent a specific part of a whole. They are an alternative method to express a division between two numbers, where the dividend is called numerator and divisor is called denominator.
We can add, subtract, multiply or divide fractions with each other. In addition, we can raise a fraction at a given power exactly as we do with integers. The rules for each operation are as follows:
When we add or subtract two or more fractions with the same denominator, only numerators are added/subtracted while the denominator does not change. In symbols, we have:
When adding or subtracting two or more fractions with different denominators, we first write the fractions involved in the operation at the same denominator and then we add/subtract them using the method above. In symbols, we have
It is better if we use the LCM of denominators as a common denominator as this avoids the necessity of further simplifications.
When two or more fractions are multiplied, all numerators are multiplied separately and all denominators are also multiplied separately. The two numbers obtained represent the numerator and denominator of the product. In symbols, we have
In division of two fractions, the second fraction is inverted down and eventually the multiplication rules are applied. In symbols, we have
This rule derives from the fact that division is a multiplication by the inverse.
When a fraction is raised in a certain power, both numerator and denominator of the given fraction are raised in that power. The general rule applied in this case is
In addition, we can use the PEMDAS Rule (see the Arithmetic Expressions Calculator for more info about this rule) in operations with fractions as well, when more than one operation with fractions is involved in a certain expression. For example, in the expression
we first find the value of division and then we do the subtraction. Hence,
