1617 / 2 = ??
The easiest way to look at this problem (and get better at doing them in your head) is to break the problem into two steps:
1600 / 2 = 800
We know that 16/2 is 8, add the 2 zeros we skipped, and we have 800
Now for the remaining 17:
We know that 16/2 = 8 and 18/2 = 9, therefore 17/2 has to be in the middle of those two numbers.
17/2 = 8.5
Now add the 800 + 8.5 and you have: 808.5, which is your answer
