Equivalent decimal to thirteen twenty fifths?

Answer 1

If you don't want to punch this question in on the calculator, the easiest way to work it out is to break it down into numbers that are easier to manage. Consider, it's fairly easy to divide numbers by 100, and 25 is a factor of 100. So if we multiply the fraction by 4/4 (which is perfectly valid, as 4/4 = 1, and multiplying by 1 does not affect the value), we get we get:

13/25 * 4/4 = 52 / 100

52/100 is somewhat easier to work out, as all you need to do is move the decimal point over two digits, giving you 0.52
