Not necessarily. Take this example:
89 ÷ 44
The rounding rules are clear. 89 goes to 90, 44 goes to 40, 90 ÷ 40 = 2.25
Compatible numbers can be altered by the relationships between them. 89 is close to 90, 44 is close to 45, 90 and 45 have a relationship that is easy to compute.
90 ÷ 45 = 2
In this case, the estimate provided by compatible numbers is closer to the real total than the one provided by rounding.

Are compatible numbers and rounding different And in what ways?
Yes, they are a bit different, but not by much. In compatible numbers, you pick numbers that are close to make it easier to solve your problem. Here's an example: Say a Mom or Dad has $187.45 to spend buying Christmas presents for their three kids. They decide that they want to spend about the same amount of money for each kid, but it doesn't have to be exact. You could get a pencil and paper out and divide 187.45 by 3 and get 63.483333333... OR you could just round down 187.45 to 180 and divide it by 3 much easier. (Probably in your head!) The reason 180 and 3 are compatible numbers is because they divide easier since 3 goes into 18 evenly. Rounding is a bit more accurate depending on how close you need to round. 187.45 can be rounded to 187.5 if you are are rounding to the nearest tenth, or 187 if you're rounding to the nearest whole number, or 190 to the nearest tens or 200 for the nearest hundred.
Rounding to the nearest tenth of a cm?
Is the same as rounding to the nearest millimetre.
What are divisibile numbers?
Divisibile numbers means the same thing as dividing and the numbers are 2,4,6,9and 10.
Rounding off to the first digit is called?
Rounding to the first digit is simply called rounding. This will make the number equal to the same as what the number truly is.
Does the word delta mean the same thing as difference when subtracting two numbers?
"Delta" is often used to mean "the difference" between two numbers, and that is the same as subtracting. When you subtract, the answer is called the "difference."
Are the estimates always the same when you use rounding to the nearest whole number and compatible numbers?
no actually
What are compatible numbers for 504 divided by 32?
15.75
Why is rounding closer to the actual weight than compatible with these numbers 9.4 and 62.6?
Rounding is closer because the amount added to one number is the same as the amount subtracted from the other number which makes the answer match exactly.
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.
How do you find the area by rounding?
.the same but you just round the numbers first

Does rounding up mean the same thing as estimate?
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.
What is the definition of a compatible number?
this means two numbers that are the same and that can compare
What is the approximation of 66?
The approximation of 66 in numbers and systems will remain the same . It is because after rounding off also it will be 66 only.
What is the same thing about composite and prime numbers?
They are whole numbers.
Is the wep410 Bluetooth compatible with the Samsung m300 phone?
yes it is, i do believe i have the same thing
Is the nook color compatible with the nook app?
Yes definitely! They are kinda the same thing!!
