Frequently Asked Questions
How do you add fractions with different denominators?
To add fractions with unlike denominators, find the Least Common Multiple (LCM) of the denominators to create equivalent fractions with a common denominator, add the numerators, and reduce using the GCD.
How do you divide two fractions?
To divide fractions, multiply the first fraction by the reciprocal (flipped version) of the second fraction: (a/b) ÷ (c/d) = (a/b) × (d/c) = (a × d) / (b × c).
What is an improper fraction vs a mixed number?
An improper fraction has a numerator larger than or equal to its denominator (e.g. 11/4). A mixed number combines a whole number with a proper fraction (e.g. 2 3/4).
