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

unlike fractions

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

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.

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.

Do you mean "What are unlike fractions? There must be at least 2. They are fractions with different denominators such as 3/4 and 1/2. Like fractions would be fractions like 3/4 and 1/4.

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

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 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.

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

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

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

Multiply them by each other.

the fractions have different denominators

2/6

because they are the same number

What is the definition of Adding and Subtracting Like Fractions

1/4 + 1/3

Unlike fractions have denominators that are unequal, and therefore cannot be added or subtracted. If two fractions need to be added or subtracted they must first be converted to like fractions.

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.

multiply the two denominators

You must have 2 fractions or more to have unlike fractions. They are fractions with different denominators such as 7/8 and 1/2. Like fractions would have the same denominator like 7/8 and 4/8.
