Answer:
82 7/8
Explanation:
Volumes is length x width x height
L 8 1/2 x W 3/1
change 8 1/2 mixed fraction to an improper fraction of 17/2
17/2 x 3/1 = 17x3/2x1 = 51/2
Now we times 51/2 x height 3 1/4
change 3 1/4 mixed fraction to an improper fraction 13/4
51/2 x 13/4 = 51x13/2x4 = 663/8
Now they want your answer to be a simplified mixed fraction
How many times can 8 go into 663 without going over?
82 times since 82 x 8 = 656
The remainder left over is 663/8 - 656/8 = 7/8
So your answer is 82 7/8. You cannot simplify 7/8 any farther.
You can also divided 663 by 8, just remember to list your remainder as a fraction of the eighths
