You do not need to estimate it - you can calculate its exact value! 6/7 divided by 2 = 3/7

This already is a whole number. You don't need to change anything.

The best estimate of 170 would typically be to round it to the nearest ten or hundred. When rounding to the nearest ten, 170 remains 170, while rounding to the nearest hundred gives you 200. Depending on the context, if you need a rough approximation, 170 can also be estimated as 200 for simpler calculations.

51 IS a whole number and so you do not need to do any estimating!
As a whole number it would not need estimating, but it would probably be estimated to the nearest 10, which would round it to 210.
