Fraction calculator
This calculator performs basic and advanced fraction operations, expressions with fractions combined with integers, decimals, and mixed numbers. It also shows detailed step-by-step information about the fraction calculation procedure. The calculator helps in finding value from multiple fractions operations. Solve problems with two, three, or more fractions and numbers in one expression.
Result:
8 1/2 - 3/5 = 79/10 = 7 9/10 = 7.9
Spelled result in words is seventy-nine tenths (or seven and nine tenths).How do we solve fractions step by step?
- Conversion a mixed number 8 1/2 to a improper fraction: 8 1/2 = 8 1/2 = 8 · 2 + 1/2 = 16 + 1/2 = 17/2
To find a new numerator:
a) Multiply the whole number 8 by the denominator 2. Whole number 8 equally 8 * 2/2 = 16/2
b) Add the answer from previous step 16 to the numerator 1. New numerator is 16 + 1 = 17
c) Write a previous answer (new numerator 17) over the denominator 2.
Eight and one half is seventeen halfs - Subtract: 17/2 - 3/5 = 17 · 5/2 · 5 - 3 · 2/5 · 2 = 85/10 - 6/10 = 85 - 6/10 = 79/10
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(2, 5) = 10. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 2 × 5 = 10. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - seventeen halfs minus three fifths is seventy-nine tenths.
Rules for expressions with fractions:
Fractions - use a forward slash to divide the numerator by 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 integer and
fraction and use a forward slash to input fractions i.e., 1 2/3 . An example of a negative mixed fraction: -5 1/2.
Because slash is both signs for fraction line and division, use a colon (:) as the operator of division fractions i.e., 1/2 : 1/3.
Decimals (decimal numbers) enter with a decimal point . 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 of operations are:
PEMDAS - Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
BEDMAS - Brackets, Exponents, Division, Multiplication, Addition, Subtraction
BODMAS - Brackets, Of or Order, Division, Multiplication, Addition, Subtraction.
GEMDAS - Grouping Symbols - brackets (){}, Exponents, Multiplication, Division, Addition, Subtraction.
MDAS - Multiplication and Division have the same precedence over Addition and Subtraction. The MDAS rule is the order of operations part of the PEMDAS rule.
Be careful; always do multiplication and division before addition and subtraction. Some operators (+ and -) and (* and /) has the same priority and then must evaluate from left to right.
