Like fractions are fractions with the same denominators.
Like fractions have the same denominators (bottom part of fraction), unlike fractions do not.
fractions having same denominators are like fractions & others are unlike fractions
because they are the same number
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.
Like fractions can be ordered according to their numerators alone. You can ignore the denominators for the process.
As a review, similar fractions (also like fractions) are fractions having the same denominators
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.
They have the same 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.
They have the same 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.
Because you can't add or subtract fractions that have different denominators. Making them like fractions, by multiplying so the denominators are the same, you can add and/or subtract them.
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.
Because when you compare fractions with the same denominators, you do not have to find the least common denominator (LCM or LCD).
A fraction where the denominators are different EG: 1/6 and 1/4. Like fractions are when the denominators are the same EG: 1/6 and 2/6 Hope this helped :))))
To add fractions w/ common denominators, like 2/5 + 1/5, you must ONLY add the numerator, or the top numeral.
When adding fractions with like denominators, add the numerators together and put the result over the denominator. Simplify if possible.
You can convert them to equivalent fractions with like denominators, then simply compare the numerators.You might also convert each fraction to a decimal (divide the numerator by the denominator); then you can also compare them.
By the definition of like fractions, the denominators are the same.
If the fractions have the same denominator, add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible. If the fractions have different denominators, find the LCM of the denominators and convert the fractions to equivalent fractions with like denominators. Then add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible.
In fractions, you can NEVER add or subtract
