Unit fraction

Fractions with a 1 in the numerator are called unit fractions.

 


Explanation

Most people prefer calculations with integers. If a fraction must be used, they like to see integers there as well, if possible with 1 in the numerator (such as 1/3, 1/6, 1/60).

This is called the inverse of a number. From this comes the expression: division is the same as a multiplication with the inverse.

 


Unit fractions with prime numbers

If the numerator in a unit fraction is a prime number, there often emerge repetitions of the same number
