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

The numerator is the top number of a fraction that indicates how many parts of the whole are being considered.

The denominator is the bottom number of a fraction that indicates the total number of equal parts the whole is divided into.

To convert a fraction to a decimal, divide the numerator by the denominator.

A fraction is in simplest form when the numerator and denominator have no common factors other than 1.

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

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

To find an equivalent fraction, multiply or divide both the numerator and denominator by the same non-zero number.

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

To convert an improper fraction to a mixed number, divide the numerator by the denominator to find the whole number, and use the remainder as the new numerator.
