4000
It is 4000.
Estimate: 80 times 50 = 4000 Actual: 77 times 52 = 4004
4 kg = 4000 grams
4000% of 4000 =4000/100 * 4000 =160,000
It is ok, but you could get better estimates.
There is no reason to estimate: 4000 + 10 = 4010.
it is the estimated version of the answer the answer is 4,200 and yes 4,000 is a reasonable .
4000
It is 4000.
It is a 36.7347% difference.
The difference is 4000 units. Divide 4000 by 32000 to get the answer which is 12.5%.
4,000
3971 + 10123 = 4000 + 10000 = 14000.
The best estimate is, obviously, the exact answer which is 671898.4556 : anything else is less than best.A respectable estimate is 4000*175 = 4000*(7/4)*100 = 1000*(7)*100 = 700000.
3945 * 78 = approx 4000*75 = 4000*(3/4*100) = (4000*3/4)*100 = 3000*100 = 300,000
The answer here would be 2,500.
