I'm wondering if anybody might have a nice trick for me to deal with divisions with small numbers. For example I'm struggeling with cases like this : 0.024 / 0.8 = ?
Of course I can directly see that it must be something with 3 and if I do the long way of expanding the 0.024 to a bigger number I come to the right conclusion of 0.03. However, it simply takes me too much time. For multiplications with large numbers I do the trick with x 10^n and with that I'm really fast.
Maybe someone knows a nice way to 1.) avoid mistakes with the zeros after the comma and 2.) to speed up the calculation.
Thanks a lot in advance!
