Final answer:
The decimal form of 1/10 is 0.1, and there is no need for rounding since it is already at the thousandth place.
Step-by-step explanation:
The question is asking for the decimal form of 1/10, rounded to the nearest thousandth if necessary. In decimal form, 1 divided by 10 is 0.1.
This is because when dividing by powers of 10, such as 101 in this case, you move the decimal to the left by the number of zeros in the power of ten. Since there is only one zero in 101, we move the decimal point one place to the left starting from 1, which gives us 0.1. The answer does not require rounding as it is already at the thousandth place.
When dividing by powers of 10, the decimal is moved to the left by the number of zeros in the power of ten. In this case, we are dividing by 1,000, which has three zeros, so the decimal is moved three places to the left.
1/10 in decimal form is 0.1. Rounding this to the nearest thousandth gives 0.100.
