you x by 1000 i think by a calculator.

Edit: I am not a mathematician and have not looked back at maths post GCSE, so do not take my word for it.

Right:
x = 0.126
1000x = 126.126
1000x - x = 126.126 - 0.126
999x = 126
x = 126/999

I think you would times 0.126(reacuring) by a thousand.

I am not certain so do not take my word for it.

This would have been better in maths rather than gcse

n =0.1262626

1000n = 126.262626
10n = 1.262626

If you subtract you will eliminate the decimal

Presumably you had something on the left hand side to equal 125

Don't say stuff like this.

How on earth do you expect to see yourself passing with this kind of attitude?

I know it is hard as maths is not everyone's forte(it clearly is not mine)otherwise i would have given you the answer and working out straight away.

Basically, you have just got to keep trying. Also sometimes if you do not understand(sometimes maths is like that) you could just memorise the steps for a specific question and then you will get the hang of it once you have applied the same principal for similar questions-maths is after all just repetition.

There's 2 recurring numbers so you times that by 100. (because 100 has 2 zeros!)
100x=12.6262626... (multiply original number so only the recurring numbers are on the right-hand side of the decimal)
100x-x=12.6262626.... - 0.1262626... = 12.5 (Find the difference so you get rid of the recurring numbers)
So, 99x = 12.5
x=12.5/99 (You need to divide both sides by 99 to get x)
x=25/198 (multiply fraction to get integers/whole numbers)

x=25/198
Message me if you need any additional help!

http://www.mathcentre.ac.uk/topics/ :this one is good as well

this pdf probably contains the method you are looking for: http://www.cimt.plymouth.ac.uk/proje...lgcse/bka6.pdf

Ohhh okay that makes sense. I just saw the ipod vids as the first heading and clicked on them.. But yeah they're slightly time consuming. Thanks for the tips and what is a torrent btw :K

And ahahah I won't be doing A-Level Maths I can barely do GCSE Maths!

Erm could I ask you with help with one question on solving equations?
