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:

8 3/4 - 5 5/6 = 35/12 = 2 11/122.9166667

The spelled result in words is thirty-five twelfths (or two and eleven twelfths).

How do we solve fractions step by step?

  1. Conversion a mixed number 8 3/4 to a improper fraction: 8 3/4 = 8 3/4 = 8 · 4 + 3/4 = 32 + 3/4 = 35/4

    To find a new numerator:
    a) Multiply the whole number 8 by the denominator 4. Whole number 8 equally 8 * 4/4 = 32/4
    b) Add the answer from the previous step 32 to the numerator 3. New numerator is 32 + 3 = 35
    c) Write a previous answer (new numerator 35) over the denominator 4.

    Eight and three quarters is thirty-five quarters.
  2. Conversion a mixed number 5 5/6 to a improper fraction: 5 5/6 = 5 5/6 = 5 · 6 + 5/6 = 30 + 5/6 = 35/6

    To find a new numerator:
    a) Multiply the whole number 5 by the denominator 6. Whole number 5 equally 5 * 6/6 = 30/6
    b) Add the answer from the previous step 30 to the numerator 5. New numerator is 30 + 5 = 35
    c) Write a previous answer (new numerator 35) over the denominator 6.

    Five and five sixths is thirty-five sixths.
  3. Subtract: 35/4 - 35/6 = 35 · 3/4 · 3 - 35 · 2/6 · 2 = 105/12 - 70/12 = 105 - 70/12 = 35/12
    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(4, 6) = 12. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 4 × 6 = 24. In the following intermediate step, it cannot further simplify the fraction result by canceling.
    In other words - thirty-five quarters minus thirty-five sixths is thirty-five twelfths.

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.
