If the denominators are the same number, add the numerators together and put that total over the original denominator. Reduce if possible. 1/4 + 2/4 = 3/4

3/8 + 3/8 = 6/8 = 3/4

If the denominators are different numbers, it is necessary to find a common denominator. Find the Lowest Common Multiple (LCM) of the denominators (also known as the Lowest Common Denominator, or LCD) and convert the fractions to equivalent fractions with the same denominator. Now that they have the same denominator, proceed as above. 1/4 + 1/6 = 3/12 + 2/12 = 5/12

If you are struggling to find the LCM just multiply the denominators together - it just means that you will likely be working with larger numbers than if you had used the LCM.

Make the fractions equivalent then subtract

no, to add and subtract like and unlike fractions the denominator has to be the same,

In fractions, you can NEVER add or subtract

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.

it is important to learn how to add and subtract fractions because we can use it when a time comes , when we have our own business and others .

Yes.

Because to add fractions, the denominators must be equal.

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 order to add or subtract fractions, they must have the same denominator.
