press button "Convert fractions to least common denominator". Rules. Least common denominator of fractions. For reduction of fractions to the least common denominator you should: find the least common multiple of the denominators [it will be the least common denominator]; divide the least common denominator into denominators of the given ...

Steps for Adding Fractions with Unlike Denominators. 1. Identify the least common denominator by finding the least common multiple for the denominators. 2. Write equivalent fractions (making sure that each equivalent fraction contains the least common denominator (LCM)) 3. Add the equivalent fractions that you wrote in step 2. (The denominators should now be the same.)

A mixed number is a combination of a whole number and a fractional part. For example \(3 {1 \over 2} \) is a mixed number. When adding or subtracting fractions and mixed numbers the most important part is to find a common denominator. This means getting the denominators for both fractions the same. How to add and subtract fractions
