The estimate of 17.5 typically rounds to either 17 or 18, depending on the context. If you are rounding to the nearest whole number, it would round up to 18. If you're rounding to one decimal place, it remains 17.5.

The answer depends on what you wish to do with the estimate. If you wanted to divide by 25, I would suggest 175 since 175/25 = 7. If you wanted to add 315 then I would suggest 185 since 185 + 315 = 100 + 85 + 15 + 300 = 100 + 100 + 300 = 500.

The front end estimate is 200. 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 179 to 1 trillion, I would estimate it as 0.If I had to add 179 to 0.0000000001, I would use the number as given, or possibly the front end estimate. If I had to divide it by 10, I would estimate it as 180, because 180/10 = 18. If I had to divide it by 25, I would estimate it as 175, because 175/25 = 7.
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.
175*175 = 30625
175% of 64= 175% * 64= 1.75 * 64= 112
55% of 175= 55% * 175= 0.55 * 175= 96.25
13% of 175= 13% * 175= 0.13 * 175= 22.75
