For example, the decimal 3.763 when rounded to the nearest cent is 3.76. This is because the decimal can only be rounded to the last cent, not the last fraction of a cent. In a dollar, there are only a hundred cents, so any decimal must be rounded to the most accurate hundredth.
Another example could start with the decimal 0.7445. To find the nearest cent, someone would start with the number in the last decimal place, which is five.

The same rounding method happens to the five in the thousandth place.Learn more about Numbers
