Question

(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?

Answer 1

yes you need to simplify your answer! ;)

Answer 2

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

Answer 3

(6-12)*5/3^3 = -30/27
if numerator and denominator divide by 3, what is the simplify it ?

Answer 4

but 3 divided by 3 is 1 and 9 divided by 3 is 3
