OK, I understand. Give me the number
to be rounded, and I'll do that.
1000 x 40 = 40,000
20,000 --------------------------------- You need to specify a value such as ones, tens, hundreds, thousands, or ten-thousands. To get the greatest value by rounding you would do all of these, compare them and pick the greatest. 22,000 is greater than 20,000 and you get this by rounding to the thousands place.
It is the accuracy in the estimate of the constant or the effect of rounding.
800
It is 59.
90-80 is 10.
1000 x 40 = 40,000
That's the "rounding" process.
20,000 --------------------------------- You need to specify a value such as ones, tens, hundreds, thousands, or ten-thousands. To get the greatest value by rounding you would do all of these, compare them and pick the greatest. 22,000 is greater than 20,000 and you get this by rounding to the thousands place.
That's correct if rounding to the second greatest place value, but not the greatest. The greatest place value in a three digit number is the hundreds place. 849 rounded to the nearest hundred is 800.
Rounding off, 80 x 60 = 4800. The actual product is 4698.
Rounding to different numbers of significant figures, the greatest result is 22,000.21 987 round off theto its greatest value what is answer.
To round 4399 to the greatest place value, you need to look at the digit in the thousands place, which is 4. The next digit to the right is 3, which is less than 5, so the thousands place remains the same. Therefore, rounding 4399 to the greatest place value would result in 4000.
An estimate is an educated guess based on prior knowledge. Rounding off is knowing the exact value but rounding it to the nearest whole number.
It is the accuracy in the estimate of the constant or the effect of rounding.

It is 59.
