Fraction Calculator
This fraction calculator performs all basic fraction operations – addition, subtraction, multiplication, and division – and evaluates expressions with fractions. Each calculation includes a detailed step-by-step explanation.
The result:
5 5/6 - 6 1/6 = -1/3 ≅ -0.3333333
Spelled out: minus one third.How do we solve fractions step by step?
- Conversion a mixed number 5 5/6 to an improper fraction: 5 5/6 = 5 5/6 = 5 · 6 + 5/6 = 30 + 5/6 = 35/6
To find a new numerator:
a) Multiply the whole number 5 by the denominator 6. Whole number 5 equals 5 ·6/6 = 30/6
b) Add the answer from the previous step 30 to the numerator 5. New numerator is 30 + 5 = 35
c) Write a previous answer (new numerator 35) over the denominator 6.
Five and five sixths is thirty-five sixths. - Conversion a mixed number 6 1/6 to an improper fraction: 6 1/6 = 6 1/6 = 6 · 6 + 1/6 = 36 + 1/6 = 37/6
To find a new numerator:
a) Multiply the whole number 6 by the denominator 6. Whole number 6 equals 6 ·6/6 = 36/6
b) Add the answer from the previous step 36 to the numerator 1. New numerator is 36 + 1 = 37
c) Write a previous answer (new numerator 37) over the denominator 6.
Six and one sixth is thirty-seven sixths. - Subtract: 35/6 - 37/6 = 35 - 37/6 = -2/6 = 2 · -1/2 · 3 = -1/3
Both fractions have the same denominator, which is then the common denominator in the subtracting them. In the following intermediate step, the fraction cannot be simplified further by cancelling.
In other words, thirty-five sixths minus thirty-seven sixths equals minus one third.
Rules for expressions with fractions:
Fractions - Use a forward slash to separate the numerator and denominator. For example, for five-hundredths, enter 5/100.Mixed numbers Leave one space between the whole number and the fraction part, and use a forward slash for the fraction. For example, enter 1 2/3 . For negative mixed numbers, write the negative sign before the whole number, such as -5 1/2.
Division of fractions - Since the forward slash is used for both fraction lines and division, use a colon (:) to divide fractions. For example, to divide 1/2 by 1/3, enter 1/2 : 1/3.
Decimals Enter decimal numbers using a decimal point (.), and they will be automatically converted to fractions. For example, enter 1.45.

Order of Operations
Ever wondered why calculators don't just work left to right? This calculator follows the mathematical order of operations — a set of rules that ensures everyone solves expressions the same way, every time.
Popular Memory Tricks
Different regions use different mnemonics to remember this order:
* PEMDAS - Parentheses, Exponents, Multiplication, Division, Addition, Subtraction
* BEDMAS - Brackets, Exponents, Division, Multiplication, Addition, Subtraction
* BODMAS - Brackets, Order (or "Of"), Division, Multiplication, Addition, Subtraction
* GEMDAS - Grouping symbols (parentheses, brackets, braces: (){}), Exponents, Multiplication, Division, Addition, Subtraction
The Golden Rules
Rule 1: Multiplication and division always come before addition and subtraction. Think of them as the VIPs that skip to the front of the line!
Rule 2: When operations have equal priority (like × and ÷, or + and −), work from left to right—just like reading a book.
Rule 3: Parentheses change the natural order of evaluation of operations.
