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. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.

unlike fractions

Convert unlike fractions to equivalent fractions with common denominators by finding the LCM of the denominators.

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

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

The first step is to make the denominators the same.

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

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

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.

Because to add fractions, the denominators must be equal.

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.

unlike fractions

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

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

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.

Multiply them by each other.

the fractions have different denominators

2/6

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.

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

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).
