When multiply fractions, multiply the numerators together and denominators together.
-8 x 5 = -40
9 x 6 = 54
-8/9 x 5/6 = -40/54
To simplify the fraction, find the biggest number that both 40 and 54 can go into. To do this, list the factors of each.
40-
1,2,4,5,8,10,20,40
54-
1,2,3,6,9,18,27,54
The biggest number each goes into is 2
Divide both -40 and 54 by 2
-40/2=-20
54/2=27
-40/54 = -20/27
C is he correct answer
