Question from Eve, a student:

Hi, i had a problem with change 0.99999... this recurring decimal to a fraction. I know the method, but the answer I got is 1 as you can see below.

x=0.9999.....
10x=9.9999.....
10x-x=9
9x=9
x=1

Where have i done wrong?

Hi Eve,

You did nothing wrong. 0.9999... is another way of writing 1.
