Sometimes it is advantageous to express a value in round numbers. To round to a particular place, look at the digit immediately to the right of the one you want to round to. If that digit is 4, 3, 2, 1 or 0, zero it and everything to the right of it out. If that digit is 5, 6, 7, 8 or 9, increase your target digit by one and zero everything to the right of it out.
Since the number to the right of the 1 is a 9, increase the 1 to 2 and zero everything else out. 199 rounds up to 200.
Rounded to the nearest ten, 199 is approximately equal to 200.
It is: 199/200 times 100 = 99.5%
To round to the nearest hundred and ten both being 200 it leaves 9 possibilities. 195,196,197,198,199,201,202,203, and 204. The only one with digits adding up to 19 is 199.

1oooooo-200 = -199
1.000-200 = -199
To round to the nearest hundred and ten both being 200 it leaves 9 possibilities. 195,196,197,198,199,201,202,203, and 204. The only one with digits adding up to 19 is 199.
