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 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.
Are rounding and compatible numbers the same thing?
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.
Explain whether it is easier to estimate the product 13.72 x 47.28 by using compatible numbers or by rounding each factor to the nearest whole number?
Compatible numbers would be easier. Rounding gives you 14 x 47. Compatible numbers could be 13 x 50 which would be closer to the actual product.
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!

Are the estimates always the same when you use rounding to the nearest whole number and compatible numbers?
no actually
When you use compatible numbers to estimate 9.4 plus 62.6 is it closer to the actual answer then using rounding?
Not in this case.
What are compatible numbers for 504 divided by 32?
15.75
Estimate the total weight of two boxes that weight 9.4 lb and 62.6 lb using rounding and compatible numbers which estimate is closer to the actual total weight why?
Rounding the weights to 10 lb and 60 lb gives an estimated total weight of 70 lb. Using compatible numbers by rounding to 9 lb and 60 lb, the estimated total weight is 69 lb. The estimate using compatible numbers (69 lb) is closer to the actual total weight of 71.6 lb.
Use compatible numbers to estimate each difference 84 - 36?
use compatible numbers to estimate each difference 84-36
What is a compatible fraction?
Ah, a compatible fraction is like a good friend that gets along well with others. When you have compatible fractions, they have the same denominator, making it easier to add or subtract them. It's like painting a beautiful landscape with colors that blend harmoniously together. Just remember, when fractions are compatible, working with them becomes a joyful experience.
