Question

Round to the nearest tenth 639.497?

Answer 1

630.497 to the nearest tenth = 630.5

631 would be rounded to the nearest "ones" place, not tenth.

630.497 is hundreds, tens, ones, decimal point "." tenths, hundredth, thousandth.  So, if you want to round the number to the nearest "tenths place,"; if the number in the hundredth place is less than 5, you just drop everything after the tenths place without changing that number any.  If the number in the hundredth place is 5 or greater, you drop all numbers beyond the tenths place and increase the tenth place number by one. Because the number in the hundredth place is 9 (greater than 5), the 97 was dropped and the .4 was increased by one to .5
