below is step by step guide for use 3 fraction Calculator :

before using Calculator for fraction you should know formula for fraction

## Fractions Formula

1. Convert the mixed numbers to improper fractions
2. Use the algebraic formula for addition of fractions:
a/b + c/d = (ad + bc) / bd
3. Reduce fractions and simplify if possible

## Multiplying Mixed Numbers using the Multiplying Fractions Formula

1. Convert the mixed numbers to improper fractions
2. Use the algebraic formula for multiplying of fractions: a/b * c/d = ac / bd
3. Reduce fractions and simplify if possible

### 3 fraction calculator multiply formula

ab×cd=a×cb×dab×cd=a×cb×d

### Example

multiply 1 2/6 by 2 1/4

1 2/6 * 2 1/4 = 8/6 * 9/4 = 8*9 / 6*4 = 72 / 24

Reduce the fraction to get 3/1 and simplify to 3

## How to Add and Subtract Fractions

1. Check to see if the fractions have the same denominator.
2. If they don’t have the same denominator, then convert them to equivalent fractions with the same denominator.
3. Once they have the same denominator, add or subtract the numbers in the numerator.

### There are 2 ways you can add 3 Fractions

• Adding fractions with like denominators
• adding fractions with unlike denominators.

#### Adding 3 Fractions with Like Denominators

Adding 3 fractions with like denominators is easy. All you have to do is add the numerators together and keep the denominator same,

for example:

#### Adding 3 Fractions with Unlike Denominators

Adding 3 fractions with unlike denominators requires a little more work (unless you use the calculator on this page), because in order to add the 3 fractions you must first turn their unlike denominators into like denominators. You do that by finding the lowest common multiple (LCM) of the denominators.

To illustrate how you use LCM to turn unlike denominators into like denominators, let’s suppose you want to add the fractions 1/2, 2/3, and 3/4.

The first step is to find the lowest number

### Operations on Negative Numbers

Whether you are working with fractions, whole numbers or decimals, use these guidelines when adding and subtracting positive and negative numbers.
