Thread: [SOLVED] Recurring Decimal Help - 0.1575757...

I need an explanation of how to do this question

0.1(57) Where the brackets mark recurring signs.

I know you start it by saying let x = 0.157575757... just not quite sure where to go from here.

Well, if we let then Now subtract.



So

Thankyou! I got confused because I got a decimal over a fraction and didn't know what to do.

Thanks so much!!
