It depends on what place to which you are rounding. Generally, a decimal number is rounded to the nearest integer, where any number in the 10ths place greater than 4 makes you round up, and if it's 4 or less, you round down. In the case of 6.153, rounding to the nearest integer would be 6. But if you are rounding to the nearest 10th, then the answer would be 6.2, since the value in the 100ths place is a 5.
