Fraction calculator



This fraction calculator performs all fraction operations and evaluates expressions with fractions. It also shows detailed step-by-step information about the fraction calculation procedure. The calculator helps find value from multiple fraction operations with two, three, or more fractions and numbers in one expression.

The result:

7 2/9 + 6 5/6 = 253/18 = 14 1/1814.0555556

The spelled result in words is two hundred fifty-three eighteenths (or fourteen and one eighteenth).

How do we solve fractions step by step?

  1. Conversion a mixed number 7 2/9 to a improper fraction: 7 2/9 = 7 2/9 = 7 · 9 + 2/9 = 63 + 2/9 = 65/9

    To find a new numerator:
    a) Multiply the whole number 7 by the denominator 9. Whole number 7 equally 7 * 9/9 = 63/9
    b) Add the answer from the previous step 63 to the numerator 2. New numerator is 63 + 2 = 65
    c) Write a previous answer (new numerator 65) over the denominator 9.

    Seven and two ninths is sixty-five ninths.
  2. Conversion a mixed number 6 5/6 to a improper fraction: 6 5/6 = 6 5/6 = 6 · 6 + 5/6 = 36 + 5/6 = 41/6

    To find a new numerator:
    a) Multiply the whole number 6 by the denominator 6. Whole number 6 equally 6 * 6/6 = 36/6
    b) Add the answer from the previous step 36 to the numerator 5. New numerator is 36 + 5 = 41
    c) Write a previous answer (new numerator 41) over the denominator 6.

    Six and five sixths is forty-one sixths.
  3. Add: 65/9 + 41/6 = 65 · 2/9 · 2 + 41 · 3/6 · 3 = 130/18 + 123/18 = 130 + 123/18 = 253/18
    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(9, 6) = 18. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 9 × 6 = 54. In the following intermediate step, it cannot further simplify the fraction result by canceling.
    In other words - sixty-five ninths plus forty-one sixths is two hundred fifty-three eighteenths.

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 sign 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 /) have the same priority and must be evaluated from left to right.
