Why is 1.999 rounded to the nearest hundredths is 2?

Answer 1

When rounding to a specific place, take a look at the digit immediately to the right of the target, in this case, the thousandths place. If that digit is 4 or less, zero everything to the right of the target out. If that digit is 5 through 9, increase the target by one and zero everything to the right of it out. If the target is a 9, increasing it will turn it to zero and increase the digit to the left of the target by one.

If you are counting by hundredths (1.97, 1.98, 1.99, 2.00, 2.01) 1.999 is closer to 2.00 than it is to 1.99
