So the store bought 9 cases of lightbulbs and in a case, there are 48.
9 * 48 = the number of lightbulbs in the nine cases. 432 is the number of light bulbs in the 9 cases they bought in May. So then let's move on to the cases they bought in June. Do the same thing 8 * 48 is 384. So then add the two amounts together and then you will get 816 which will be your answer. I hope this helps!
Answer:
4 5/8 the answer you have is correct :)
Step-by-step explanation:
First, you want to make the mixed fraction into an improper fraction.
7 x 4 + 3 = 31 (31/4)
3 x 8 + 1 = 25 (25/8)
Now you want them both to have a common denominator.
31/4 x 2/2 = 62/8
Now you are ready to subtract!
62/8 - 25/8 = 37/8
Finally, convert 37/8 to a proper fraction.
37/8 = 4 5/8
