Fraction calculator
This fraction calculator performs all fraction operations - addition, subtraction, multiplication, division and evaluates expressions with fractions. It also shows detailed step-by-step information.
The result:
2 3/4 * 4/5 = 11/5 = 2 1/5 = 2.2
The result spelled out in words is eleven fifths (or two and one fifth).How do we solve fractions step by step?
- Conversion a mixed number 2  3/4 to a improper fraction: 2 3/4 = 2  3/4 = 2 · 4 + 3/4 = 8 + 3/4 = 11/4
To find a new numerator:
a) Multiply the whole number 2 by the denominator 4. Whole number 2 equally 2 * 4/4 = 8/4
b) Add the answer from the previous step 8 to the numerator 3. New numerator is 8 + 3 = 11
c) Write a previous answer (new numerator 11) over the denominator 4.
Two and three quarters is eleven quarters. - Multiple: 11/4 * 4/5 = 11 · 4/4 · 5 = 44/20 = 11 · 4/5 · 4 = 11/5 
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(44, 20) = 4. In the following intermediate step, cancel by a common factor of 4 gives 11/5.
In other words, eleven quarters multiplied by four fifths equals eleven fifths. 
Rules for expressions with fractions:
Fractions - write a forward slash to separate the numerator and the denominator, i.e., for five-hundredths, enter 5/100. If you use mixed numbers, leave a space between the whole and fraction parts.Mixed numerals (mixed numbers or fractions) - keep one space between the whole part and fraction and use a forward slash to input fraction i.e., 1 2/3 . A negative mixed fraction write for example as -5 1/2.
A slash is both a sign for fraction line and division, use a colon (:) for division fractions i.e., 1/2 : 1/3.
Decimals (decimal numbers) enter with a decimal dot . and they are automatically converted to fractions - i.e. 1.45.

The calculator follows well-known rules for the order of operations. The most common mnemonics for remembering this order are:
- 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 (brackets: (){}), Exponents, Multiplication, Division, Addition, Subtraction.
 - MDAS: Multiplication and Division (same precedence), Addition and Subtraction (same precedence). MDAS is a subset of PEMDAS.
 
1. Multiplication/Division vs. Addition/Subtraction: Always perform multiplication and division *before* addition and subtraction.
2. Left-to-Right Rule: Operators with the same precedence (e.g., + and -, or * and /) must be evaluated from left to right.
Fractions in word problems:
- Closer to one 
 Here are two sums: A=1/2 + 1/3 and B=1/5 + 1/3. Which of the two sums is closer in value to 1? You must show your work and state clearly whether the answer is A or B. - Same fractions 
 I remember that 2/2 is equal to 1. 3/3 is equal to 1. Where is the fraction 4/4 located on the number line? - Fractions 82848
