You can do it by hand, too.
First look at the repeating digits; there are two of them. Then you multiply the number by 10 to the power of how many repeating digits there are. Since there are two repeating digits, do 10^2, which is 100. Let N be the repeating number. 100N = 34.54545454545454545454.... N = 0.34545454545454545454.... Now subtract the two. ![]() ^ You can see that the repeating 5's and 4's get cancelled out. If you put 342/990 into simplest terms, you get 19/55. There you go. =] |
