The following question has two parts. first, answer part a. then, answer part b. part a a high school athlete ran the 100 meter sprint in 13.245 seconds. round the time to the nearest tenth. enter the answer in the box. part b explain how you arrived at the answer. include any rules that you followed.

The answer to Part A is 13.25.
And the answer to Part B is hen you round to the nearest 10th the steps are nearly always the same:Identify which place value you are rounding to. The smaller the place value, the more accurate the final result will be.Look to the next smallest place value, the digit to the right of the place value you're rounding to. For example, if you want to round to the nearest ten you'd look at the ones place.If the digit in the next smallest place value is less than five (0, 1, 2, 3, or 4), you leave the digit you want to round to as-is. Any digits after that number (including the next smallest place value you just looked at) become zeros, or drop-off if they're located after the decimal point. This is called rounding down.If the next smallest place value is greater than or equal to five (5, 6, 7, 8, or 9), you increase the value of the digit you're rounding to by one (+1). Just like before, any remaining digits before the decimal point become zeros, and any that are after the decimal point are dropped. This is called rounding up.
