Yes if the number includes decimals

Instead of rounding each number to a given place value, we round whatever number is in the front.

To the nearest tenth, 77.5 To the nearest whole number, 78

Yes

The answer depends on the purpose of rounding. This, in turn, depends on what is being done with the number.

Yes.Because you know where the decimals on the number end, it is a rational number. If you are just rounding the number, and it's really 50.85624861913756843168713843134313764673388 .... etc., with the decimals continuing forever without a pattern, then it is irrational.

it rounds to that number because the number 4 is lower so they take that number out of the picture.

Rounding to ones eliminates decimals. 14.9 rounds to 15

Most decimals comprise an infinite number of digits: some are repeating and other non-terminating. If you did not round them, most people would still be writing out their first decimal number - and they would still be at it when they died!

There is no such number because decimals are infinitely dense. That is, between any two decimals, there are infinitely many decimals.

The only way to make equivalent decimals to decimals is by adding trailing zeroes to the end of the number. Therefore, 0.105 is equal to 0.1050, or 0.10500, and so on.

if the number is less than 5 round toward the number 1 if the number greater than a 5 round toward the number 9
