Question

Tucker's Road Paving Company used 646.5 tons of cement to pave 4 miles of roadway. To the nearest hundredth of a ton, how much cement, on average, did the company use per mile?

Answer 1

161.63 tons

Explanation:

Cement used per mile = total cement used / total miles

646.5 tons / 4 = 161.625 tons

161.63 tons to the nearest hundredth

the hundredth is the second number after the decimal place. To convert to the nearest hundredth, look at the number after the hundredth (the thousandth). If the number is greater or equal to 5, add 1 to the hundredth figure. If this is not the case, add zero

the thousandth term is 5, so 1 would be added to 2
