How can estimating with compatible numbers help you find the quotient?
it makes it easier when u round
Why does it make sense to round a mixed number to the nearest whole number when estimating a sum or difference Could you round to the nearest one half instead?
Some people find it easier to add or subtract whole numbers but yes, you could round to the nearest half.
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.
What is the difference in what you have to do for rounding and estimating?
Estimating is just an educated guess. For example, if you have to solve the problem 102.17 plus 266.18, you would make an educated guess. An educated guess would be 100+ 270 which equals 370. When you are rounding, you will usually get instructions to round a certain number. It is knowing the exact value, but finding the nearest whole number. For example: Round to the nearest hundredth 4.6781 If you are rounding to the nearest hundredth, you are trying to round the number 8, since it is in the hundredths spot. To round 8, look at 1. Is it greater than 5? If the number is greater than 5, round the number up by 1. If the number is smaller than 5, the number remains the same.
What is easier to round to the hundreds or tens?
If it is a 3 or more dugit number, it is easier to round of to 100. The reason is that we can directly replace the last 2 digits by zero.

How much times does 38 go into 81 and estimate 38 to a easier number?
round 38 to 40 and get 80 by multiplying. Then, do 38 x 2 and you’d have to round to get about the same answer.
Why is estimating Not as helpful when multiplying very small numbers such as 0.007 and 0.053?
Estimating is not as helpful when multiplying very small numbers because the numbers aare very easy to answer
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 estimating sums mean?
It means to round a number to the nearest whole number, tens, hundreds, etc.
What is a possible method for estimating 8.035x0.1544?
1) Round each number 2) Do the multiplication
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?
Normally when estimating quotients you should round both numbers in the same direction whereas for products you should round the two numbers in opposite directions.
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.
What is the estimate of 206?
As a whole number it would not need estimating, but it would probably be estimated to the nearest 10, which would round it to 210.
