If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators.

When adding unlike fractions, find the LCM of the denominators and convert them to it.


When adding two fractions with unlike denominator's which of these steps is the first step?

The first step is to make the denominators the same.


What are unlike fractions?

Unlike fractions are fractions having unlikedenominators, e.g., 1/4 and 1/6.


What do like and unlike fractions mean?

Like fractions have the same denominators (bottom part of fraction), unlike fractions do not.


What is the definition to unlike denominators?

unlike denominators: the bottom number of a fraction. to have unlike denominators you must have two fractions with a different number on the bottom of each fraction.


What is 1 over 2 plus 2 over 5 by adding fractions with unlike denominators?

When you add or subtract fractions with unlike denominators why do you have to find LCM?

Because to add fractions, the denominators must be equal.


Are the steps for like and unlike denominators the same or different?

It depends what you are doing with the fractions. If you are multiplying or dividing fraction, the denominators do not need to be the same and the calculation can be carried out immediately. If you are adding or subtracting fractions, the denominators must be the same; if you have different denominators, the fractions must first be changed into equivalent fractions with the same denominator. When the denominators are the same (or have been made the same as equivalent fractions from being different) the calculation can be carried out.


Fractions with different denominators are called?

unlike fractions


What the difference between like and unlike fraction?

fractions having same denominators are like fractions & others are unlike fractions


Explain how comparing fractions with like denominators differs from comparing fractions with unlike denominators?

Because when you compare fractions with the same denominators, you do not have to find the least common denominator (LCM or LCD).


How is the least common multiple used when adding and subtracting fractions?

When adding and subtracting unlike fractions, find the LCM of the denominators and convert them to it. In this case, it's called the least common denominator, but it's the same process.

What are fractions with unlike denominators mean?

The denominator is the bottom number in a fraction. Fractions like 1/3 and 1/4 have different numbers on the bottom. Those are unlike denominators.


What is an common multiple of the denominators for two or more fractions?

Multiplying the denominators together of two or more unlike fractions will get you a common multiple.


Adding mixed numbers with unlike denominators?

First convert the mixed numbers into "top heavy (or "improper) fractions". Now multiply each of the improper fractions by each other - this makes the denominators the same. Now you can add both the fractions together (and cancel down if necessary).
