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.
Do you round up or down 60.33333?
To round to the nearest whole number, round down to 60. To round to the nearest hundred, round up to 100.
What is 18.2665 round to in the nearest hundredth?
18.27 ( 5 and up round up 4 and down round down :P )
How do you round up 15.334 up or down to 2 decimal places?
Always look at the next digit to the right of where you want to round up or down to. If the next digit is 5 or more, you round up. If it's 4 or less, you round down. In this case, you would round the number down to 15.33
What is the difference between rounding and estimating in math?
Rounding is when you make the number go up by 1 when it is 5 or more in a one digit number. When it is a two digit number, the number in the ones place has to be 5 or more to round up which means to make the number go up. When a number in the ones place is less than 5, you have to make the number goes down. For example, if you have the number 59, you would round up and it would be 60 or if you had the number 52, you would go down and the number would be 50. Rounding is also done after you solve an equation. For example, when you have an equation like 25+61, you would first have to solve the equation normally and then you round the answer. 25+61=86. 86 is rounded to 90 and that is your answer for an equation that is needed to be rounded. Estimating is when you have an equation and you round up or down before you solve the equation.
How do you do estimating sums?
When estimating sums, it is best to round to the nearest round number. If the last place on the right is less than 5, then round down. If the last place on the right is 5 or more, then round up. For example, 43+88. You would round the 43 down to 40 and the 88 up to 90. The estimated sum would 130.
Estimating fractions to the nearest whole number?
If the fraction is less than half, round down. If the fraction is half or greater, round up.

How is estimating quotients different from estimating products?
Estimating quotients is like trying to guess how many slices of cake you'll get from a whole cake, while estimating products is like trying to figure out how much money you'll have after buying a certain number of cakes. In both cases, you're making an educated guess based on the numbers involved, but the end result is either a quotient (division) or a product (multiplication). So, in a nutshell, estimating quotients involves dividing and estimating products involves multiplying.
Do you round both numbers of estimating?
Yes but, if you can, you should try to round one up and the other down. Unless that results in rounding well away from the number. For example, 48*62 Exact answer = 2976 If you round 48 up to 50, 62 down to 60 Estimate = 50*60 = 3000 (estimation error = +0.8%) But if you had 48*68 Exact answer = 3264 Round up and down: 50*60 = 3000 (estimation error = -8.1% ) Round down and up: 40*70 = 2800 (estimation error= -14.2%) Round up and up: 50*70 = 3500 (estimation error = +7.2%) The last still has a large error but it is the smallest of the these.
Round off 430?
