Answer:
The stock of soda will last for 8 days
Step-by-step explanation:
Change the denominator to a common one, i.e. change 1/5 to 2/10
Now make both numbers to improper fractions; you get 9/10 of a bottle per day and 72/10 bottles of soda in stock.
With a common denominator, we can now simply ignore it. Divide 72 by 9 to get 8 days.
