Converting fractions to any kind of decimal is done in exactly the same way: divide the numerator by the denominator.

The reverse of converting a recurring decimal to a fraction is done:

Look at the digits that recur in the decimal. Count how many there are and then put the recurring digits as the numerator of a fraction with that number of 9s as the denominator.

eg to convert 0.33333.... to a fraction, see that the recurring decimal is the digit 3, thus the fraction would be 3/9 = 1/3.

eg to convert 0.09090909... to a fraction, see that the recurring decimal is 09 (or 9) and there are 2 digits (the leading 0 is important in counting the number of digits), thus the fraction is 09/99 or 9/99 = 1/11.

eg: to convert: 0.142857142857.... to a fraction, see that the digits 142857 recur and there are 6 of them, thus it is 142857/999999 which reduces down (simplifies) to 1/7.

How does a nurse use decimals?

A strong working understanding of fractions and decimals is essential for nurses. They must be familiar enough with fractions and decimals to quickly and accurately divide, multiply, add and subtract dosages as well as convert fractions to decimals and vice versa. Conceptual understating of fractions and decimals is essential since half doses, extra doses and time-delayed dosages must be calculated correctly. Nurses also need to know how to convert fractions and decimals to percentages in order to explain medication instructions accurately and easily to their patients.
