What is 0.0005681818 as a fraction?

Answer 1

0.0005681818 as a fraction is 2,840,909/50,000,000

If you want to know what the repeating decimal (repeating 18's) is, the answer is: 556875/990000000.

Find this by multiplying the number by 100 (10^2, since there are two digits that repeat), then subtract the original number. The decimal point shifts by 2 places, so all of the 18's 'cancel'.

So you have the original number x, and then subtracted: y = 100x - x = (100 - 1)x = 99x, so x = y/99.

Divide the result by 99 and the equivalent number is: 0.0556875/99, then multiply both numerator and denominator by the appropriate power of ten to get an integer in both numerator and denominator. In this case, 10^7.
