(6-12)*5/3^3 I keep getting -30/9, but the answers says -10/9. I think they did some cancelling, but what do you cancel?

    i know that the 3,6,and 12 can cancel, but if i cancel the 3 out from the denominator would'nt i be left with 1^3? and that would make it 1 not 9

    \[(6-12)*5/3^{3}\] \[-30/3*3^{2}\] \[-10/3^{2}=-10/9\]
