Question

In what ways is the measurement 3.2 m like 3.20 m? How is
it different?​

Answer 1

3.20 is much more accurate than 3.2 .

Explanation:

3.2 m is way different than 3.20 m , It is because

We can't measure any length accurately , and thus we are having different devices used to measure different lengths with different precision .

In the case of 3.2 , device used can accurately measure the length one place after the decimal. In this device we can't say the digit after 2 means that it can be 1,2,.... . Thus this device is less accurate as compared to second one.

In case of 3.20 , device can accurately measure the length two places after the decimal and in this device we can confidentially say that digit after two is 0. This device is more accurate than First one.

Thus, they are different because 3.20 is much more accurate than 3.2 .
