Question

Round 18.123 to the nearest hundredth

Answer 1

18.100

If you ask '' How do I solve these questions?'' I say:

We look at the tens digit to find the nearest hundred. If the number is 1,2,3 or 4, the tens and ones digit is reset. If it is 5,6,7,8 or 9, another hundred is added to the hundreds place of the number. The remaining tens and hundreds digits are reset.
