The front end estimate is 800. 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 779 to 1 trillion, I would estimate it as 0.
If I had to add 779 to 0.0000000001, I would use the number as given, or possibly the front end estimate. If I had to divide it by 7, I would estimate it as 770, because 770/7= 110. If I had to divide it by 10, I would estimate it as 780, because 780/10 = 78.
The answer is 780
7.79 = 779/100
19 x 41 = 779
900 would be a fair estimate
You could estimate is as 0.5
The factors of 779 are: 1 19 41 779
779/210=3.7095.... So the answer is 779 is 371% of 210
-779
779 + 192 = 971
779%7.79 % * 100% = 779%
779 kg is approximately 1717 pounds.
779 = 19 x 41
43.2778
779 ÷ 41 = 19
779 meters = 851.9 yards.
324 + 779 = 1103
