Answer:
0.3 millimeters
Explanation:
The place value of numbers after the decimal point is determined by its position.
- The first number after the decimal point is the tenth digit
- The second number after the decimal point is the hundredth digit
- The third number after the decimal point is the thousandth digit
We can continue in like manner.
Given the number:
0.311 millimeters.
To round it to the nearest tenth
First, determine the tenth digit: The tenth digit is 3
Next, determine if the digit after it is up to 5. If it is 5 and above, we round up otherwise we do not.
Since the digit after 3(1) is not up to 5, we write our answer.
Therefore, the thickness of the shell to the nearest tenth is given below:
- 0.311 millimeters =0.3 millimeters (to the nearest tenth)
