Is ³⁹¹/₁₀₀₀ a Mixed, Whole Number or Proper fraction?

A mixed number is made up of a whole number (whole numbers have no fractional or decimal part) and a proper fraction part (a fraction where the numerator (the top number) is less than the denominator (the bottom number). In this case the whole number value is empty and the proper fraction value is ³⁹¹/_1000.

Can all decimals be converted into a fraction?

Not all decimals can be converted into a fraction. There are 3 basic types which include:

Terminating decimals have a limited number of digits after the decimal point.

Example: 1356.37 = 1356 ³⁷/₁₀₀

Recurring decimals have one or more repeating numbers after the decimal point which continue on infinitely.

Example: 8655.3333 = 8655 ³³³³/₁₀₀₀₀ = ³³³/₁₀₀₀ = ³³/₁₀₀ = ¹/₃ (rounded)

Irrational decimals go on forever and never form a repeating pattern. This type of decimal cannot be expressed as a fraction.

Example: 0.967713135.....
