  1. Step 1: Make sure the bottom numbers (the denominators) are the same.
  2. Step 2: Add the top numbers (the numerators), put that answer over the denominator.
  3. Step 3: Simplify the fraction (if needed)

What is the rule when adding fractions?

To add or subtract fractions

they must have the same denominator (the bottom value)

. If the denominators are already the same then it is just a matter of either adding or subtracting the numerators (the top value). If the denominators are different then a common denominator needs to be found.

How do you add and subtract fractions step by step?

Step 1: Find the Lowest Common Multiple

What are the 4 steps of adding and subtracting fractions?

Step 1: Find the Lowest Common Multiple

How do you add fractions with different denominators step by step?

  1. Cross-multiply the two fractions and add the results together to get the numerator of the answer. Suppose you want to add the fractions 1/3 and 2/5. …
  2. Multiply the two denominators together to get the denominator of the answer. …
  3. Write your answer as a fraction.

What are the steps to subtracting fractions?

  1. Make sure the bottom numbers (the denominators) are the same.
  2. Subtract the top numbers (the numerators). Put the answer over the same denominator.
  3. Simplify the fraction (if needed).

How do you add fractions examples?

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.

How do you solve fractions examples?

A

fraction compares two numbers by division

. To conduct basic operations, keep in mind that any number except 0 divided by itself is 1, and 1 times any number is itself. That is, , and 1 × 5 = 5. Thus, any number divided or multiplied by a fraction equal to one will be itself.

How do you add with different 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.

What do you call fractions with different denominators?


Unlike fractions

: Fractions with different denominators are called, unlike fractions.

Who do you add and subtract fractions?

We can only add or subtract fractions if they have

the same denominators

. So we’ll need to find the lowest common denominator before we add or subtract these fractions. Once the fractions have the same denominator, we can add or subtract as usual.

How do you figure out fractions?

To work out a fraction of a number, all you need to do is

divide that number by the denominator of the fraction, then multiply your result by the numerator of the fraction

. For instance, if we wanted to find out what 3/8 of 24 is, we would divide 24 by 8 (the denominator of the fraction).

How do you solve adding fractions?

Step 1: Make sure the bottom numbers (the denominators) are the same. Step 2:

Add the top numbers (the numerators)

, put that answer over the denominator. Step 3: Simplify the fraction (if needed)
