Adding and Subtracting Fractions

A fraction represents a part of a whole and is written as 'a/b', where 'a' is the numerator (part) and 'b' is the denominator (whole).

Adding fractions means combining the parts represented by the fractions. To add fractions with the same denominator, add the numerators and keep the denominator the same.

Subtracting fractions means finding the difference between the parts represented by the fractions. To subtract fractions with the same denominator, subtract the numerators and keep the denominator the same.

To add fractions with different denominators, first find a common denominator, convert the fractions, and then add the numerators.

To subtract fractions with different denominators, first find a common denominator, convert the fractions, and then subtract the numerators.

A common denominator is a shared multiple of the denominators of two or more fractions, allowing them to be added or subtracted.

The first step is to check if the fractions have the same denominator. If not, find a common denominator.
