Q:

# How are decimals rounded to the nearest cent?

A:

A decimal is rounded to the nearest cent by rounding it to the nearest hundredth of a dollar, which is a cent. Because there are 100 cents in a United States dollar, rounding to the nearest cent would require finding the nearest hundredth.

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. Five, unlike four and lower numbers, must be rounded up. This changes the number in the next decimal place up to a five. So the decimal is now .745. The same rounding method happens to the five in the thousandth place.

To add decimals, first write down the numbers, one below the other, with the decimal points in line with each other. If the numbers have different numbers of digits, add zeros to shorter numbers to equalize the length. Then add from right to left using column addition.

A nonterminating decimal refers to any number that has a fractional value (numbers to the right of the decimal point) that will continue on infinitely. The most well-known example of one of these numbers is pi; another example is 1/3, which is 0.333 with the three repeating forever. A nonterminating decimal is indicated by placing a short bar (ellipsis) over the final two decimal values that are recorded.

From right to left, take each digit in the base 16 number and multiply it by 16^n, where "n" is the number of places to the left of the rightmost digit, then sum the results together to get the base 10, or decimal, value. For the rightmost digit, n is 0.
