How can you make and express measurements both accurately and precisely?

When level of precision is very very less.

Explanation:

Accuracy is defined as the closeness of a measured value to a standard or known value.

For Example: If the mass of a substance is 52 kg and one person weighed 56 kg and another person weighed 51 kg. Then, the weight measured by second person is more accurate.

Precision is defined as the closeness of two or more measurements to each other.

For Example: If you weigh a given substance five times and you get 2.6 kg each time. Then the measurement is said to be precise.

Level of precision is determined by the maximum number of decimal places.

When the level of precision is very very less, the measurement can be considered as most precise and most accurate.

For Example: The actual value of the volume of substance is 81.0 mL and the values measured by 2 students is 81.1 mL and 81.001 mL. So, the value by second student is most precise and most accurate.
