Round 45.0378 to the nearest thousandth.
The correct answer and explanation is:
To round 45.0378 to the nearest thousandth, you need to look at the digit in the fourth decimal place, which is 8 in this case.
The process of rounding involves checking the digit in the place you want to round to (the thousandth place in this case, which is the third decimal place), and then determining whether the next digit (in the fourth decimal place) is 5 or greater. If it is, you round up the thousandth place by one. If it is less than 5, you leave the thousandth place unchanged.
Here’s the breakdown for 45.0378:
- The digit in the thousandth place is 7.
- The digit in the ten-thousandth place is 8.
Since 8 is greater than 5, you round up the 7 in the thousandth place by 1. This makes the rounded number 45.038.
So, the rounded value of 45.0378 to the nearest thousandth is 45.038.
