To round the number 7.892 to the nearest thousandth, we look at the digit in the ten-thousandths place, which is the fourth digit to the right of the decimal point.
In this case, the number is 7.892:
- The thousandths place is the third digit (2).
- The ten-thousandths place is the fourth digit (the second 9 in the 892).
Since the digit in the ten-thousandths place (9) is 5 or greater, we round up the thousandths place (2) by 1.
So, 7.892 rounded to the nearest thousandth becomes 7.893.
The closest option given in the choices is not available, but the correct rounded answer is 7.893.
