**FRACTION** is essentially a number presented as the ratio of two Integers, e.g.: 2/3, 5/7, 1/4, 11/5, or in symbolic form: A/B, where A is called NUMERATOR and B is called DENOMINATOR. Fraction with Numerator less than the Denominator is called **PROPER** Fraction, e.g., 2/3, 1/2, 32/33; otherwise the Fraction is called **IMPROPER** one (3/2, 2/1, 33/32 are examples of Improper Fractions).

Any Improper Fraction could be presented as MIXED NUMBER, containing Integer and Proper Fraction. In our examples:

- 5/2 = 2 1/2 (this notation actually means: 2 1/2 = 2 + 1/2)
- 2/1 = 2 (this is actually an Integer: 2/1 = 2 + 0/1)
- 33/32 = 1 1/32

Fractions Arithmetic is based on simple rules:

- Addition: A/B + C/D = (A*D + B*C) / (B*D)
- Subtraction: A/B - C/D = (A*D - B*C) / (B*D) -
- Multiplication: A/B * C/D = (A*C) / (B*D)
- Division: (A/B) / (C/D) = (A*D) / (B*C)

**3 Fractions** calculation could be reduced to a sequence of **2 Fractions** calculations, performed in certain order, namely: from the left to right. Also, Division and Multiplication operators take precedence over Addition and Subtraction. For example:

2/3 + 3/7 + 1/6 = (2/3 + 3/7) + 1/6

2/3 + 3/7 * 1/6 = 2/3 + (3/7 * 1/6)

2/3 * 3/7 * 1/6 = (2/3 * 3/7 ) * 1/6

2/3 / 3/7 / 1/6 = (2/3 / 3/7 ) / 1/6

In order to calculate 3 Fractions online follow the steps outlined below (in this example we calculate: 1/3 * 1 1/2 + 3/4):

Step 1. Open Web Browser and navigate to the site: www.webinfocentral.com/Math/Fractions.aspx

Step 2. Enter the 1st number in the text box titled 'Fraction1'. In general, it could be any proper/improper fraction, mixed number or just integer. In our example it is 1/3.

Step 3. Select the arithmetic operator (in our case it is a Multiplication “*”) using the drop down control, located just below the text box (marked with little triangle pointing downward)

Step 4. Enter Mixed Number (1 1/2) in the second text box marked Fraction 2.

Step 5. Select the second arithmetic operation (“+”) using the lower drop down and enter the 3rd Fraction (3/4) in the text box marked Fraction3. In case you do not have a 3rd Fraction just leave the text box blank.

Step 6. Click on the button on the screen marked with "=" sign to get the result: 1 1/4 and corresponding decimal equivalent: 1.25
