Fraction calculator
This fractions calculator performs all fraction operations - addition, subtraction, multiplication, division and evaluates expressions with fractions. It also shows detailed step-by-step information.
The result:
11 - 6 5/8 = 35/8 = 4 3/8 = 4.375
The spelled result in words is thirty-five eighths (or four and three eighths).How do we solve fractions step by step?
- Conversion a mixed number 6 5/8 to a improper fraction: 6 5/8 = 6 5/8 = 6 · 8 + 5/8 = 48 + 5/8 = 53/8
To find a new numerator:
a) Multiply the whole number 6 by the denominator 8. Whole number 6 equally 6 * 8/8 = 48/8
b) Add the answer from the previous step 48 to the numerator 5. New numerator is 48 + 5 = 53
c) Write a previous answer (new numerator 53) over the denominator 8.
Six and five eighths is fifty-three eighths. - Subtract: 11 - 53/8 = 4.375 = 35/8
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 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 /) have the same priority and must be evaluated from left to right.
