Q: How do you add and subtract fractions in math?

Write your answer...

When you want to add or subtract unlike fractions.

because its just one of the rules of math :)

it stay the same when you subtract fractions and when you add fractions.

Math is related to fractions. if you look in a math book or just online then one of the math topics is fractions. You learn how to divide, multiply, add and subtract, simplify and more about fractions and what to do with them.

You need a common denominator in order to add or subtract fractions.

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.

Numerators

Often in Math, fractions are used to add, subtract, multiply, divide, or indicate the magnitude of measurements that will be involved in those operations. They can be used as numbers whenever the authentic number is not an integer.

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 .

Find theLeast Common Denominator (LCD)Find the equivalent fractions.Add or subtract the fractions and add or subtract the whole numbers.Write your answer in lowest terms.

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.

Yes.

Because to add fractions, the denominators must be equal.

You add or subtract (or use other operators) depending on what is required.

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

To add and subtract fractions, you need common denominators. To find the common denominator, take the LCM of the denominators you wish to add or subtract.

The same as with positive ones. Make sure they have the same denominator and add or subtract their numerators.

When you want to add or subtract fractions.

Whether the denominators are common or not.

To add and subtract fractions, you need common denominators. To find the common denominator, find the LCM of the denominators you wish to add or subtract.

Convert them to equivalent fractions with like denominators, then proceed.

because it would be diffcult to understand.[you don't add or subtract the demonters]
