Lin had 90 flyers to hang up around the school. She gave 12 flyers to each of three volunteers. Then she took the remaining flyers and divided them up equally between the three volunteers

Umm, assuming in this case it would be 0.4646464646464646...

Then you would just assign it a variable in the beginning:

x = 0.46464646...

Then multiply it by 100, to get:

100x = 46.46464646464646...

Now you just want to subtract x from 100x, or

46.464646464646464646... - 0.46464646464646...

Which would result in 99x = 46.

Now just divide 99 from both sides to get:

x = 46/99

So it would be 46/99.

I think.
