Rounded Fraction of Pi
Date: 10/10/2001 at 22:55:23 From: Tim Subject: The rounded fraction of pi I just want like 20 digits into pi. What would the fraction (division problem) be for that?

Let's add a few more digits: 3.1415 = 3 1415/10000 = 3 283/2000 = 6283/2000 Do you see the pattern? Start with as many digits as you like. Break the part after the decimal point into a fraction where the denominator is a power of 10. Simplify the fraction, if you can. Then convert back to an improper fraction. You can do this for any number of digits that you like. Does this help? - Doctor Ian, The Math Forum http://mathforum.org/dr.math/
