Description

This calculator divides two fractions. It accepts proper, improper, mixed fractions and whole number inputs. If they exist, the solutions and answers are provided in simplified, mixed and whole formats.

There general steps to divide fractions are described below.

If the inputs are mixed fractions or whole numbers, convert them to improper fractions.
Flip or swap the divisor. This is also known as the reciprocal of the fraction. This turns the division operation into multiplication.
Multiply the left and right numerators to obtain the answer's numerator.
Multiply the left and right denominators to obtain the answer's denominator.
Simplified and Mixed Number Answers:
Find the Greatest Common Divisor (GCD)
Divide the answer's numerator and denominator by the GCD to get the simplified solution.
If the answer is greater than one, then a mixed solution exists. Simply divide the numerator by the denominator. The mixed number's whole part is self explanatory. The mixed number's fraction is the remainder over the original denominator.

Instructions/How To

This calculator will automatically update the answer or solution when any of the inputs change. The inputs include the whole number, numerator or denominator inputs fields for both the dividend and divisor.

Select the type of fraction or whole number. Do not select either field for improper or proper factions. This is the default. Selected Mixed for mixed fractions and whole for whole numbers.
Enter the left fraction or dividend. This the fraction to the left of the division operand.
Enter the right fraction or divisor. This is the fraction to the right of the operand.
Observe the step by step solution and various answers.

Note: If viewing this page on a desktop or laptop, the numerator and denominator inputs can be changed with the mouse wheel, up and downs spinner buttons and keyboard arrow keys. The mobile and smart phone version does not support these options.

Inputs

Parameter	Type	Description
Left Fraction	Not applicable	Refers to the fraction or number which is left of the division sign. This is the dividend.
Right Fraction	Not applicable	Refers to the fraction or number which is right of the division sign. This is the divisor.
Mixed	Check Box	Select to enter an mixed fraction or number. This is a number with a whole number, numerator and denominator.
Whole	Check Box	Select to enter a whole number. This is a number with only a whole number.
Whole	Edit Box	The whole part of the mixed fraction or number. This is restricted to integer values.
Numerator	Edit Box	The upper or top part of the fraction. This is restricted to integer values.
Denominator	Edit Box	The lower or bottom portion of the fraction. This is restricted to integer values.

Outputs

Parameter	Description
Improper Conversion	If the fraction is mixed, the steps to convert to an improper fraction are displayed.
Improper Fraction	If the fraction is mixed, the values of the final improper fraction.
Division	Shows the final division step before the reciprocal of the divisor is determined.
Multiply	Shows the final multiplication step. This step shows how division has been converted to multiplication.
Answer	Shows the solution. Note, this solution is not simplified.
Greatest Common Divisor	This is used to simplify the answer. The biggest or largest integer value which will divide the numerator and denominator without producing a fraction.
Divide By GCD	Shows the numerator and denominator being divided by the GCD to reduce the fraction.
Answer (Simplified)	The solution in proper or improper format.
Answer (Mixed)	If the solution is an improper fraction, the converted mixed fraction is displayed. The mixed fraction show the fraction with the whole part in addition to the left over part of the fraction.

Error Messages

Parameter	Description
Invalid Input	This error is displayed when the numerator or denominator has any of the following conditions: 1) The field is blank or empty. 2) The field contains a string which not an integer value. 3) Any value in the calculations exceeds 900000000000000.
