Question

Every day, the Sandoval Family Restaurant serves 5/6 of a bottle of soda to their customers. How many days will 7 1/2 bottles of soda last?

Answer 1

Answer:

9 days

Step-by-step explanation:

1 day: 5/6        2 days:  10/6       3 days:   15/6        4 days:  20/6   5  days: 25/6

6 days:  30/6        7 days:  35/6         8 days:  40/6       9 days: 45/6

If you divide 45 and 6 by 3 you get 15/2.  If you put 15/2 into a mixed number you would get 7 1/2.  So 9 days would be your answer.

Answer 2

Answer:

7 1/2 bottles will last 9 days

Step-by-step explanation:

To answer this, divide '7 1/2 bottles' by '5/6 bottle per day:"

 7 1/2 bottles

-----------------------

 5/6 bottle/day

The unit "bottle"/"bottles" cancel, and so we are left with

 7 1/2 day

-------------------  and this is equivalent to   15 days/2  divided by 5/6 OR

    5/6

 15 days/2 times 6/5:

15(6)

--------- days = 18/2 days = 9 days (answer)

2(5)

7 1/2 bottles will last 9 days.
