What is the difference of Estimating and Rounding?

Question

Tell me please its for my cousans

Answer 1

Estimating means you round the numbers to calculate the approximate answer.

Rounding your answer is when you calculate the exact answer and then round it to a certain place value.

Answer 2

Estimating is guessing what the answer will be.

Rounding is getting the answer to significant figures, or to certain decimal places.

Example:

1.53+3.10+3.111 -------> You can guess by quickly adding the numbers in your head. Just by looking at this, I notice the numbers to the left of the decimal. 1 + 3 + 3 = 7. Then, just quickly add the decimals. I am estimating on first look that the number will be around 7.8. In fact, the answer is 7.741.

12.194020 -------> Round to the thousandth. Thousand is 3 zeros. The question is asking to give us 3 decimal number. We see that 194 are 3 numbers, and the 4th number is a 0. If it was 5 or above, it would be 195. Look:

12.19460702--------> Round to the thousandth. You see the 6 after the 4? That means the answer is 12.195.

Answer 3

You estimate an answer. Say 512 + 490 is around 1000. You round terms or an answer, but you have to get the exact amount first. 512 rounded to the nearest hundred is 500, 490 rounded to the nearest hundred is 500. 512 + 490 = 1002 which, when rounded to the nearest hundred is 1000.

Answer 4

Rounding is simply to the next integer up or down. Estimating is a sophisticated guess.

Answer 5

An estimate is an educated guess.

Rounding is a reduction in the precision of a measurement.

Answer 6

You round a number to something easy to work with. You then use these rounded to numbers to estimate.

Answer 7

estimating is an educated guess and rounding is
which number is closest to.



got it??????
