Not in this case.
Rounding factors can lead to underestimates or overestimates: the outcome depends on the rounding.
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.
220.46 lbs. The actual conversion of 1 kilogram is equal to 2.204622622 pounds. For everyday use, rounding to 2.2 should be enough. One pound is 0.45359237 kilogram, or 0.45 kg for everyday use.
Well, darling, a reasonable estimate for 776 divided by 38 would be around 20.4. Just divide the nearest hundreds place numbers, and you'll get pretty close to the actual answer. But hey, who's counting anyway? Just remember, math is like a recipe - sometimes you can eyeball it and still come out with a decent result.
the purpose of rounding numbers is that you can get closer to the actual answer

Rounding off, 80 x 60 = 4800. The actual product is 4698.
The Answer will be lower the the actual sum

2 x 6300 = 12,600 The actual answer is 12,508.
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.
Actual answer = 1078. Rounding to the nearest 10 = 20+50=70
