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:

76*.8 = 304/5 = 60 4/5 = 60.8

Spelled out: three hundred four fifths (or sixty and four fifths).

How do we solve fractions step by step?

Conversion a decimal number to a fraction: 0.8 = 8/10 = 4/5

a) Write down the decimal 0.8 divided by 1: 0.8 = 0.8/1
b) Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.)
0.8/1 = 8/10
Note: 8/10 is called a decimal fraction.

c) Simplify and reduce the fraction
8/10 = 4 * 2/5 * 2 = 4 * 2/5 * 2 = 4/5
Multiply: 76 * 0.8 = 76 · 4/1 · 5 = 304/5
The first operand is an integer. It is equivalent to a fraction 76/1. Multiply both numerators and both denominators. Then simplify the resulting fraction to its lowest terms GCD(304, 5) = 1. In the following intermediate step, the fraction cannot be simplified further by cancelling.
In other words, seventy-six multiplied by four fifths equals three hundred four fifths.

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.
