Let's go through each answer choice and eliminate the choices.
a) 6(2/3) = 4, this is less than 6, making it our correct answer, but still go and check each answer b) 6(2/3) again = 4, this is less than 6, making this answer choice wrong. c) 6(3/2) = 9, this is greater than 6, making this answer choice wrong. d) 6(3/3) = 6, this is equal to 6, making this answer choice wrong.
First you would subtract 2 to get d/3 by itself. On the left side you would have h-2 and one the right d/3 (h-2=d/3). Then you divide by 3 to get d by itself. So the answer is h/3-2/3=d
