How are estimating and rounding different?
Estimating is a guess that should be close to the answer. Round is rounding a number up to the nearest ten, hundred. Example $345.89 round to the nearest dollar is $345.
What does rounding to the nearest cent means?
The nearest cent is the same as the nearest hundredth since 1 cent is 1/100 of a dollar. The nearest hundredth. 2.336 rounds to 2.34
When you round an amount to the nearest dollar and to the nearest 10 dollars can the rounded amounts be the same?
Yes they can. Consider the values $9.51 & $10.34 - to the nearest dollar, they would be $10. This would also be the result of rounding to the nearest $10.
What is better rounding off to nearest ten or rounding off to nearest hundred?
In whole numbers, rounding to the nearest ten is better. And in decimals, rounding to the nearest hundreth is more accurate.
What is the answer if you round 219.49 and 279.97 and 234.95 to the nearest dollar then add?
Well, darling, if we round 219.49, 279.97, and 234.95 to the nearest dollar, we get 219, 280, and 235, respectively. Adding those rounded numbers together gives you a grand total of 734. So, go ahead and treat yourself with that extra dollar you saved from rounding!
