Adding and Subtracting Fractions Rules!

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

The least common denominator is the smallest multiple that two or more denominators share, used to add or subtract fractions with unlike denominators.

An improper fraction is a fraction where the numerator is greater than or equal to the denominator, such as 11/7.

A proper fraction is a fraction where the numerator is less than the denominator, such as 3/4.

To convert a mixed number to an improper fraction, multiply the whole number by the denominator, add the numerator, and place that result over the original denominator.

The first step is to find the least common denominator (LCD) for the fractions.

The least common multiple is found by identifying the smallest multiple that is common to two or more numbers.

To add fractions, ensure they have the same denominator, then add the numerators and keep the denominator the same.

To subtract fractions, ensure they have the same denominator, then subtract the numerators and keep the denominator the same.

Simplifying a fraction means reducing it to its lowest terms, where the numerator and denominator have no common factors other than 1.
