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:

12 5/8 ÷ 3 19/24 = 303/91 = 3 30/913.3296703

Spelled result in words is three hundred three ninety-firsts (or three and thirty ninety-firsts).

How do we solve fractions step by step?

  1. Conversion a mixed number 12 5/8 to a improper fraction: 12 5/8 = 12 5/8 = 12 · 8 + 5/8 = 96 + 5/8 = 101/8

    To find a new numerator:
    a) Multiply the whole number 12 by the denominator 8. Whole number 12 equally 12 * 8/8 = 96/8
    b) Add the answer from previous step 96 to the numerator 5. New numerator is 96 + 5 = 101
    c) Write a previous answer (new numerator 101) over the denominator 8.

    Twelve and five eighths is one hundred one eighths
  2. Conversion a mixed number 3 19/24 to a improper fraction: 3 19/24 = 3 19/24 = 3 · 24 + 19/24 = 72 + 19/24 = 91/24

    To find a new numerator:
    a) Multiply the whole number 3 by the denominator 24. Whole number 3 equally 3 * 24/24 = 72/24
    b) Add the answer from previous step 72 to the numerator 19. New numerator is 72 + 19 = 91
    c) Write a previous answer (new numerator 91) over the denominator 24.

    Three and nineteen twenty-fourths is ninety-one twenty-fourths
  3. Divide: 101/8 : 91/24 = 101/8 · 24/91 = 101 · 24/8 · 91 = 2424/728 = 8 · 303 /8 · 91 = 303/91
    Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 91/24 is 24/91) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the following intermediate step, cancel by a common factor of 8 gives 303/91.
    In other words - one hundred one eighths divided by ninety-one twenty-fourths is three hundred three ninety-firsts.

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.
