Frequently Asked Questions
How do you add fractions?
To add fractions: 1) Find a common denominator (usually the LCM), 2) Convert fractions to equivalent fractions with the common denominator, 3) Add the numerators, 4) Keep the common denominator, 5) Simplify if possible.
What is a common denominator?
A common denominator is a shared multiple of the denominators of two or more fractions. The least common denominator (LCD) is the smallest positive number that all denominators divide into evenly.
How do you add fractions with different denominators?
To add fractions with different denominators, first find the least common multiple (LCM) of the denominators, then convert each fraction to an equivalent fraction with the LCM as the denominator, and finally add the numerators.
