How do you find the answer to this math problem? 3 1/3 divided by ? = -8
Turn the mixed number into an improper fraction and let ?=x
%28%283%2A3%2B1%29%2F3%29%2Fx=-8
%2810%2F3%29%2Fx=-8
x%2810%2F3%29%2Fx=-8x
10%2F3=-8x
%28-1%2F8%29%2810%2F3%29=%28-1%2F8%29%28-8x%29
-10%2F24=x
-5%2F12=x
Happy Calculating!!!

3 1/3 divided by ? = -8

[3 1/3]/x = -8
(10/3)/x = -8
(10/3) = -8x
x = - (10/24)
x = -5/12

(3 1/3)/x=-8
(10/3)/x=-8 now cross multiply.
-8x=10/3 cross multiply again.
-24x=10
now divide by -24.
x=10/-24 now reduce by dividing by 2.
x=-5/12 answer.
proof
(10/3)/(-5/12)=-8 now invert 5/12 & multiply.
(10/3)(-12/5)=-8
-120/15=-8
-8=-8
