Final answer:
197 estimated to the nearest integer is 198. This is determined by looking at the digit immediately after the decimal point, and since it's 9, we round up from 197.
Explanation:
Estimating a number to the nearest integer means rounding it off to the closest whole number. For the given number 197.989, we look at the digit immediately after the decimal point to determine how to round it. Since the digit is a 9 (which is 5 or greater), we round up the number 197 to 198. Therefore, 197 estimated to the nearest integer is 198.
This principle applies to other numbers as well. For example, with a number like 201.15, since the digit after the decimal (1) is less than 5, the number rounds down, keeping it at 201. But with a number like 203.733, the digit after the decimal is 7, so it rounds up to 204. This method of rounding is straightforward and applies similarly to all other numbers.
