Fraction calculator



This fraction 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.

The result:

1.45 = 29/20 = 1 9/20

Spelled result in words is twenty-nine twentieths (or one and nine twentieths).

How do we solve fractions step by step?

  1. Conversion a decimal number to a fraction: 1.45 = 145/100 = 29/20

    a) Write down the decimal 1.45 divided by 1: 1.45 = 1.45/1
    b) Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.)
    1.45/1 = 14.5/10 = 145/100
    Note: 145/100 is called a decimal fraction.

    c) Simplify and reduce the fraction
    145/100 = 29 * 5/20 * 5 = 29 * 5/20 * 5 = 29/20

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.
