Addition: Mixed Numbers

Study Guide

Key Definition

A mixed number is a number expressed as the sum of a whole number and a fraction. You can perform basic operations such as addition and subtraction on them just like any other number.

Important Notes

Convert all mixed numbers into improper fractions before adding or subtracting.
If the denominators are different, find a common denominator before adding or subtracting the fractions.
If the denominators are the same, simply add or subtract the numerators.
After performing the operation, convert the resulting improper fraction back into a mixed number.

Mathematical Notation

$\frac{a}{b}$ represents a fraction where $a$ is the numerator and $b$ is the denominator.

Remember to use proper notation when solving problems

Why It Works

The process of converting mixed numbers into improper fractions makes it easier to perform operations. Once the operation is complete, you can convert the result back into a mixed number for easier understanding.

Remember

Always convert mixed numbers into improper fractions before adding or subtracting.

Quick Reference

Mixed Number:$a \frac{b}{c}$ where $a$ is a whole number and $\frac{b}{c}$ is a fraction.

Improper Fraction:$\frac{a}{b}$ where $a$ is greater than $b$.
