Question

If a 10-pound sack of potatoes costs $6.55, how much would 1 pound cost? Round your answer to the nearest cent. 

Answer 1

If we know price of 10 pounds sack and we want to know price of 1 pound we have to just divide price of 10 by 10, so:
6.55=10=0.655
Now we can round it
0.655=0.66 because the last digit is 5.
Answer is 0.66
