The denominator will always stay the same Adding Fractions. The steps to add fractions with unlike denominators are. Multiply the numerator and denominator to get like denominators.
Do the same with the remaining fraction s. First we use visual models to learn that the fractions need converted into like fractions using equivalent fractions. To add the two fractions we have to do the following three steps.
If the denominators are not the same you must find the common denominator by finding the. We want to add fractions with different denominators. Start out by multiplying the numerator of the first fraction by the denominators of all the other fractions.
The next lesson concentrates on how we find the common denominator. Steps for Adding Fractions with Unlike Denominators. Find the least common multiple LCM for the denominators.
Multiply the numerator of the second fraction by denominator of the first fraction. Least common multiple LCM. Make sure the bottom numbers the denominators are the same.
Students do several exercises using visual models and try to look for a pattern in the common denominators. Then reduce the fraction. Do the same with the second fraction and add this value to the first.
