Please could you help me with all the steps necessary to do this sum ?
Divide 621 over 0.31 and round the answer to 2 decimal places.
Thanks
$\displaystyle \frac{621}{0.31} = \frac{62100}{31}$
Now do your division.
I get 2003.2258064516
Now, the third decimal place is a 5, and there are numbers past this. So by the way I was taught, we round up the second decimal place:
$\displaystyle \frac{621}{0.31} = 2003.23$
(If it had turned out to be exactly 2003.225 I would round down to 2003.22.)
