## How do you add and subtract fractions step by step?

Step 1: Find the Lowest Common Multiple (LCM) between the denominators. Step 2: Multiply the numerator and denominator of each fraction by a number so that they have the LCM as their new denominator. Step 3: Add or subtract the numerators and keep the denominator the same.

## How do you add and subtract fractions with different denominators?

Adding and Subtracting Fractions with Unlike Denominators
1. STEP ONE: Get a common denominator.
2. STEP TWO: Add or subtract the numerators.
3. STEP THREE: Simplify the result if needed. Notice that 3/27 can be simplified, since the numerator and denominator are both divisible by 3.
4. And that’s all there is to it! Final Answer:

## What are the 4 steps of adding and subtracting fractions?

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

Here’s the way to do it:
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.

## Do you add the denominator when adding fractions?

To add fractions there are Three Simple Steps:

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 possible)

## How do you subtract fractions for dummies?

To use the traditional way to subtract fractions with two different denominators, follow these steps:
1. Find the least common multiple (LCM) of the two denominators. …
2. Increase each fraction to higher terms so that the denominator of each equals the LCM. …
3. Substitute these two new fractions for the original ones and subtract.

## How do you solve mixed fractions?

Step 1: Multiply the denominator with the whole number. Step 2: Add the numerator to the product obtained from step 1. Step 3: Write the mixed fraction with the sum obtained from step 2 as the numerator and the denominator of the original fractional part of the mixed fraction.
