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.
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.
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.
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.
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!

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.
no actually
Not in this case.

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.
