What is the difference between estimating and compatible numbers?

The difference between compatible numbers and estimation is that in estimation you round to the nearest ten or hundred most of the time. Compatible numbers are numbers that are easy to compute mentally.
Some examples of compatible numbers when doing division are 400 and 10, 36 and 6, 2400 and 12, and 64 and 8
2400 and 12 are compatible because when doing this division (2400/12), we can quickly divide 24 by 12 to get 2 and put two zeros at the end to get 200
Some examples of compatible numbers when doing multiplication are 200 and 40, 1100 and 40, 25 and 4.
1100 and 40 are compatible because we can quickly do this multiplication by multipling 11 and 4 to get 44 and add three zeros at the end to get 44000
Hope this helps!

What is the difference between compatible numbers and rounding?
Rounding is going to the nearest tens, hundreds, thousands etc., depending on the problem. Compatible numbers are numbers the work well with each other. Both of these are estimating.
What is 179 divided by 9 as estimating quotient from compatible numbers?
19.8889
What is the difference between a compatible number and rounding numbers?
rounding numbers is to nearest ten or hundred and compatible numbers are when you can do nearest 5
What is the difference between rounding front end numbers and compatible numbers?
If I were multiplying I would like to round to tens so I can "annex" the zeroes. If I were adding I would like numbers that would equal 0 like 3+7 or 5+5 or 2+8. They are compatible numbers.
What is the difference between two numbers is 10 If the numbers are doubled what is What is the difference between them?
the difference is also doubled

How can estimating with compatible numbers help you find the quotient?
it makes it easier when u round
What is a compatible fraction?
What are compatible fractions? Round the whole number to the closest compatible number to the denominator. Compatible numbers are numbers that are close in value to the real number that would make it easier to find an estimate calculation. compatible numbers are numbers that are a like or can compared like fact families! Compatible numbers When estimating, compatible numbers are numbers that are close in value to the actual numbers, and which make it easy to do mental arithmetic. In mathematics, compatible numbers are the numbers that are easy to add, subtract, multiply, or divide mentally. Compatible numbers are close in value to the actual numbers that make estimating the answer and computing problems easier. We can round the numbers to the nearest ten, hundred, thousand or ten thousand to make them compatible numbers. For instance, if we have to add 493 and 549, we can make the numbers compatible by rounding them up to the nearest tens or hundreds. 490 and 550 (rounded to the nearest tens) or 500 and 500 (rounded to the nearest hundreds) are much easier to solve. So, we know the answer is about 1040 or 1000. Let us see some examples to understand how we can perform subtraction, multiplication and division using compatible numbers. Subtraction: Find the difference between 376.5 and 612.2 Here, we cannot find the difference between 376.5 and 612.2 easily as they are not compatible. So, we make the numbers compatible by rounding both the numbers to the nearest tens. Multiplication: Find the product of 24.3 and 18.7. It is difficult to find the product of 24.3 and 18.7 mentally and quickly. So, we use compatible numbers and find the which is closer to the actual answer. Division: Divide 856 by 33. To find the answer to 856 ÷ 33, will take us time as we need to divide to get the answer. However, if we make the numbers compatible, we can mentally find an answer close to the actual answer as shown. Fun Facts Compatible numbers help in simplifying the calculation of an estimate only.
