## Key Concepts

**Fraction Addition**- If \(a,b,\) and \(c\) are numbers where \(c\ne 0\), then \(\frac{a}{c}+\frac{b}{c}=\frac{a+c}{c}\).
- To add fractions, add the numerators and place the sum over the common denominator.

**Fraction Subtraction**- If \(a,b,\) and \(c\) are numbers where \(c\ne 0\), then \(\frac{a}{c}-\frac{b}{c}=\frac{a-c}{c}\).
- To subtract fractions, subtract the numerators and place the difference over the common denominator.
