Answer 1

These decimal values increase in powers of 10 as you move to the right of the decimal place. For example: the value of 1 is measured with an accuracy of 1/10000, so we shall write it as 1.0000 indicating that we are accurate to within 1/10000th of what we measured. In your example, the nearest 100th would be 2 decimal places away, or 46.00 indicating that your measurements are only accurate to within 1/100th of a unit.
