Adding Fractions With Common Denominators
Adding Fractions With Common Denominators is a skill on Pengi from Lesson 13: Adding and Subtracting Fractions and Mixed Numbers in Saxon Math, Course 3.
Key Concepts
Property To add or subtract fractions that have common denominators, add or subtract the numerators and leave the denominators unchanged. For example, $\frac{a}{c} + \frac{b}{c} = \frac{a+b}{c}$.
Examples When adding, combine the numerators: $\frac{3}{4} + \frac{3}{4} = \frac{6}{4}$, which simplifies to $1\frac{1}{2}$. When subtracting, find the difference of the numerators: $\frac{5}{8} \frac{2}{8} = \frac{3}{8}$. For a quick addition, $\frac{2}{7} + \frac{4}{7} = \frac{6}{7}$.
Explanation Think of it like counting pizza slices of the same size! If you have 3 eighths of a pizza and your friend gives you 2 more eighths, you just add the number of slices. The size of the slice (the denominator) stays the same. You now have 5 eighths. It’s that simple!
