That depends on what PLACE your rounding that number to.--THAT is actually your choce on what number place you want to round the whole number of: 38,721,830, unless the directions specify what place you should round a number to. -There IS NO GIVEN ROUNDING PLACE....however; for money, we round after the decimal place in the hundredths place....( for Ex: with $1.25 , the 5 cents is in the hundredths place, after the decimal, so first, you MUST learn your number line .....remember? Ones place, Tens place....and so on? You can get a book about it @ your school or the library, or if your in grade school ask your teacher or your parents to go over a STANDARD U.S. Number Line with you and then teach you to round off whole numbers (to the left of decinmal place and negative numbers to the right of the decimal place) and negative numbers...
4 million.
Instead of rounding each number to a given place value, we round whatever number is in the front.
Rounding the number.
An Estimate is basically a guess. Rounding is when you have an answer and you shorten the answer to a given number of digits. eg $27482 would round to $27500 to the nearest hundred dollars.
That's the "rounding" process.
Less
Infinitely many. It depends on the accuracy to which the numbers were given prior to rounding.
5.18
20 rounding units. 20.0 rounding tenths 19.8 rounding hundredths 19.76 rounding thousandths 19.765 rounding tenthousandths 19.7649 rounding hundred thousandths
It depends on what you are rounding by. If you are rounding by ten-thousands=80000 If you are rounding by thousands=85000 If you are rounding by hundreds=84700 If you are rounding by tens=84650
That depends on how you are rounding: Rounding up = 6.33 Rounding down = 6.32 Rounding nearest = 6.32
That would depend on what you were rounding it to. If rounding to the nearest whole number, then it does not need rounding. If rounding to the nearest ten, it would be 420. If rounding to the nearest hundred, it would be 400.
