Adding and Subtracting Fractions

A fraction represents a part of a whole. It consists of a numerator (top number) and a denominator (bottom number).

The numerator represents the number of parts we have.

The denominator represents the total number of equal parts the whole is divided into.

Equivalent fractions are different fractions that represent the same value or proportion of a whole.

Add the numerators and keep the same denominator.

Subtract the numerators and keep the same denominator.

You need to find a common denominator.

A common denominator is a shared multiple of the denominators of two or more fractions.

The least common multiple of 4 and 6 is 12, so the common denominator is 12.

3/4 + 1/4 = 4/4 = 1 (whole).
