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:

9 1/6 - 5 1/3 = 23/6 = 3 5/63.8333333

The spelled result in words is twenty-three sixths (or three and five sixths).

How do we solve fractions step by step?

  1. Conversion a mixed number 9 1/6 to a improper fraction: 9 1/6 = 9 1/6 = 9 · 6 + 1/6 = 54 + 1/6 = 55/6

    To find a new numerator:
    a) Multiply the whole number 9 by the denominator 6. Whole number 9 equally 9 * 6/6 = 54/6
    b) Add the answer from the previous step 54 to the numerator 1. New numerator is 54 + 1 = 55
    c) Write a previous answer (new numerator 55) over the denominator 6.

    Nine and one sixth is fifty-five sixths.
  2. Conversion a mixed number 5 1/3 to a improper fraction: 5 1/3 = 5 1/3 = 5 · 3 + 1/3 = 15 + 1/3 = 16/3

    To find a new numerator:
    a) Multiply the whole number 5 by the denominator 3. Whole number 5 equally 5 * 3/3 = 15/3
    b) Add the answer from the previous step 15 to the numerator 1. New numerator is 15 + 1 = 16
    c) Write a previous answer (new numerator 16) over the denominator 3.

    Five and one third is sixteen thirds.
  3. Subtract: 55/6 - 16/3 = 55/6 - 16 · 2/3 · 2 = 55/6 - 32/6 = 55 - 32/6 = 23/6
    It is suitable to adjust both fractions to a common (equal, identical) denominator for adding, subtracting, and comparing fractions. The common denominator you can calculate as the least common multiple of both denominators - LCM(6, 3) = 6. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 6 × 3 = 18. In the following intermediate step, it cannot further simplify the fraction result by canceling.
    In other words - fifty-five sixths minus sixteen thirds is twenty-three sixths.

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.
