Is it easy to add fractions with different denominators?
Related articles: Adding fractions is easy if the denominators are the same, but adding fractions with different denominators requires care. If you set up an algebraic equation to add fractions with different denominators, you need to find the lowest common denominator first.
When do you add and subtract fractions in Excel?
It’s easy to add and subtract fractions when the numbers on the bottom are the same. These are called the denominators. However, sometimes the denominators are different. You use equivalent fractions to make them the same. A common multiple of 2 and 3 is 6. So, for each fraction we need an equivalent fraction with a denominator of 6.
