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.
