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:

3 3/7 * 2 = 48/7 = 6 6/7 ≅ 6.8571429

Spelled out: forty-eight sevenths (or six and six sevenths).

How do we solve fractions step by step?

Conversion a mixed number 3 3/7 to an improper fraction: 3 3/7 = 3 3/7 = 3 · 7 + 3/7 = 21 + 3/7 = 24/7

To find a new numerator:
a) Multiply the whole number 3 by the denominator 7. Whole number 3 equals 3 ·7/7 = 21/7
b) Add the answer from the previous step 21 to the numerator 3. New numerator is 21 + 3 = 24
c) Write a previous answer (new numerator 24) over the denominator 7.

Three and three sevenths is twenty-four sevenths.
Multiply: 24/7 · 2 = 24 · 2/7 · 1 = 48/7
The second operand is an integer. It is equivalent to the fraction 2/1. Multiply both numerators and both denominators. Then simplify the resulting fraction to its lowest terms GCD(48, 7) = 1. In the following intermediate step, the fraction cannot be simplified further by cancelling.
In other words, twenty-four sevenths multiplied by two equals forty-eight sevenths.

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.
