Study Notes

What is a Fraction?

A fraction represents a part of a whole.
The whole can be any number, value, or thing.
Fractions are written as one number over another, separated by a line.

Parts of a Fraction

Consists of a numerator and a denominator.
Numerator: Represents the selected part of the whole. It is placed above the fractional bar.
Denominator: Indicates the total number of parts the whole is divided into. It is placed below the fractional bar.

Types of Fractions

Vulgar: Common or regular fractions written as one number over another.
Proper: Numerator is less than the denominator, representing less than one whole.
Improper: Numerator is greater than or equal to the denominator, representing one whole or more.
Mixed: A combination of a whole number and a proper fraction.

Adding and Subtracting Fractions with Like Denominators

Adding: Add the numerators, keeping the denominator the same.
Subtracting: Subtract the numerators, keeping the denominator the same.

Adding and Subtracting Fractions with Unlike Denominators

Find the least common multiple of the denominators (common denominator).
Rewrite each fraction using the common denominator.
Add or subtract the numerators.
Keep the common denominator.

Adding and Subtracting Mixed Fractions

Convert mixed fractions to improper fractions.
Find the common denominator.
Rewrite each fraction using the common denominator.
Add or subtract the numerators.
Keep the common denominator.
Simplify the result if possible.
