Adding Fractions with Different Denominators
Adding Fractions with Different Denominators is a skill on Pengi from Lesson 2: Adding Rational Numbers in Big Ideas Math, Advanced 1.
Key Concepts
To add fractions with the same denominator, combine the numerators: $\frac{a}{b} + \frac{c}{b} = \frac{a+c}{b}$.
To add fractions with different denominators, first find a common denominator ($bd$): $$\frac{a}{b} + \frac{c}{d} = \frac{ad}{bd} + \frac{cb}{bd} = \frac{ad + cb}{bd}$$.
