Frequently Asked Questions
How do I add fractions with different denominators?
To add unlike fractions, first find the Lowest Common Multiple (LCM) of the denominators to convert them into like fractions, then add their numerators.
What is the difference between a numerator and a denominator?
The numerator is the top number that shows how many parts we have, and the denominator is the bottom number that shows total equal parts in the whole.
How do I convert a mixed fraction into an improper fraction?
Multiply the whole number by the denominator, then add the numerator to this product. Put this result over the original denominator.
