What do you do when a decimal is stuck in repeat?

Atm its like this:

0.4444 So Im guessing its going to keep doing that.

[Magus]

0.4 That's it.

Connor, it really depends on the question. I'd write it as a fraction, if you can. Or otherwise just write it as 0.44444 with a dot (.) over the last 4 in the decimal. It's grand to just write 3 or 4 digits after the decimal (0.444 with a dot over the last 4).

The number of places after the decimal you use depends on your instructor. If its college-level work, then the number of places you would record would be determined by the number in your calculations that has the least number of decimal places (the least precise value). Otherwise, just ask your teacher how much they care about precision.

I'd learned a line over the repeating part if it's a nonterminating repeating decimal.
Though, unless it says "to x place value", you could write it as .4 with the line/dot(?)

[Malcolm Tucker]

Yeah I prefer using the dot, as I use the line on top for the conjugates so I don't wanna use both like. Just me though, you can do either or.

i learned to pout a line above the repeated number
......................._
for single its like .4
............ __
doubles .65

Yeah, that :P I didn't know how to type it out

[Malcolm Tucker]

Or in my case I do this:

blankspacee..
0.1313131313

It comes up every year in my the state exams here. We are given something like

0.6343434343.....and have to use the sum to infinity for a geometric progression to express it as a rational number.

Thanks guis.
