A percentage is always out of 100 and so if this is converted to a decimal, it is always out of 1.The number has simply been divided by 100.So to change a decimal to a percentage you simply multiply by 100.So 0.41 x 100 =41%
The front end estimate is 8000. But estimating a single number, in isolation and without context, is a complete waste of time. It all comes down to the context of what needs to be done with the number.If I had to add 8244 to 1 trillion, I would estimate it as 0.If I had to add 8244 to 0.0000000001, I would use the number as given, or possibly the front end estimate. If I had to divide it by 41, I would estimate it as 8241, because 8241/41 = 201. If I had to divide it by 10, I would estimate it as 8240, because 8240/10 = 824.
The closest estimate is the exact answer. For any other estimate, you can do better with more effort.150*83 = approx 100*3/2*82 = 100*3*41 = 100*3*40 = 12000.
Yes. This is because 158 is approximately 160 and 41 is approximately 40. 160/40 = 4, therefore 4 is a good estimate of 158/41.
well yes you can so you round to 158 to 160 and divid 41to40and divid but now you know how to do the actual division so do you see how close the estimate it is .
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.
Yes, you round 158 to 160, and 41 to 40, and divide. Now, do the actual division (perhaps with a calculator), to see how close the estimate is. Practice with several similar divisions, to get a "feel" of how much rounding will result in how much of an error.
