Fractions

A fraction represents a part of a whole and is expressed as a ratio of two integers, with a numerator (top number) and a denominator (bottom number).

The numerator indicates how many parts of the whole are being considered.

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

1/2

1/3

1/4

To add fractions with the same denominator, keep the denominator the same and add the numerators.

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

Subtract fractions by finding a common denominator, converting the fractions, and then subtracting the numerators.

A mixed number is a whole number combined with a proper fraction, such as 1 1/2.
