3 is not a good estimate for 3.4 times 0.09 because, the result of 3.4 times 0.09 is 0.306.
0.306
The answer being 0.5456, the digit 2 can not be a good estimate since it is not close.
If I assume that you're talking about 158 / 41 then my quick answer is yes, it is a good estimate. 4 times 41 is 164 which is closer to 158 than 3 times 41 (123) and 5 times 41 (205). Final summary: 4 is a good estimate for 158 / 41 because it is the closest whole number to the real answer.
the answer would have had 5 digits
He is good at math
It's off by an order of magnitude. Should be near 27,000, not 2,700. Checking now... it's 26,187, to be precise.
10 times 351 = 3510 The real answer will be 351 more than that. Estimate 3861
No
21,000

There is no good reason. There are times when you would and times when you would not.

This depends on which context you are using 'does good' in. For example, if you said that a person 'does good' things, it would be grammatically correct. But if you said someone 'does good' without inferring that they are doing good THINGS, and not just GOOD, then it would not be using correct English. Isn't the English language confusing at times?!? :)
It would be if 0.09 rounded to 1. But since 0.09 rounds to 0.1, estimate 0.3
if i am correct, i am sure we have declared war about 4 or 5 times. Good question.
"He is good" is correct. 'He' is singular, 'are' is for plurals.
"You were looking good" is grammatically correct.
Incorrect. Correct is, Some is correct.
