Which math sentence is in the same fact family as :
( X*Y = Z )
A. Z*Y = X
B. Z*X = Y
C. Y (divided by) Z = X
D. Z (divided by) Y = X 
One way to find out is to use numbers for the letters 

X*Y = Z  could stand for
2*3 = 6  if X=2, Y=3, and Z=6

Then the above would be:

Which math sentence is in the same fact family as :
( 2*3 = 6 )
A. 6*3 = 2
B. 6*2 = 3
C. 3 (divided by) 6 = 2
D. 6 (divided by) 3 = 2
 
Now it is easy to see that A, B, and C are false, and only D is true.

Answer: D
