When the actual answer is not a solution that can be applied in real life and a higher number is required.
For example, consider the number of coaches required to transport 60 children when each coach can take 40. The actual answer is 1.5 but you cannot get 1.5 coaches so the real-world answer is 2.
I'd choose 20 and 30 and estimate the product at 600. The actual answer is 625.
It is not always the case. I would not bother to estimate 3+5 before getting the actual answer because (for me) the effort involved is the same.Having said that, with complicated calculations, having an estimate can help decide whether it is likely that your calculation is correct.
Well, in texting, you might say "u wud" But, in the actual English language, you would say "You'd"
A liter is more than a quart. Some of you might recognize this symbol > if you are in a certain grade then you may recognize that symbol in this case it would be a greater than symbol. Thank you for reading my answer.
Your sum might be less than fifty and you would rather round to forty than zero.
199 over 198 estimate = 1 actual answer would be greater than 1 35 over 17 estimate = 1 actual answer would be greater than 1
There is no good reason. There are times when you would and times when you would not.
If you were a car mechanic and your actual amount came in lower than the estimate, your customer would think he or she got a good deal.
By rounding off.
No. A better estimate would be 380. The actual total is 379.
The estimation would be 960. The actual answer is 962.
The estimate would be 1/5 or 20%. The actual is 5/28 or 17.86%
I would bet on the eraser.
