Perhaps, you can try by:
dividing 2 by 3 and get: 0.6 repeated
so, this time, try adding a zero by the denominator, which turns the fraction into 2/30.
If you solve this, you may end up with 0.06 repeated.
2/3 = 0.6
2/30 = 0.06
Sorry, add the negative sign behind the fraction...
Which gives you -2/30
