If you divide on a calculator, you get 7.440366972. You should round to 7.3, or at least I THINK you should, because the next number after 4 is another 4, and as my math teacher says with rounding, " 5 or more, let it soar. 4 or less, let it rest. " meaning if its 5 or more, go UP! If its less than 5, let it go DOWN! Hope this helps!
Aye Sir!
