    Answer : The order from least precise to most precise is,

    21000 grams < 915 meters < 8.43 inches < 5.426 seconds

    Step-by-step explanation :

    Precision : It 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 1.8 kg each time. Then the measurement is said to be precise.

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

    or,

    Level of exactness in a number’s digits, such as number 54.6 having precision 1 (one decimal digit).

    A number with end zeroes (“00”) has a negative precision, such as 600 having precision -2, or 5,000 as precision -3.

    A whole number (not ending in “0”) has precision 0.

    From the given measurements we conclude that, the order from least precise to most precise is:

    21000 grams < 915 meters < 8.43 inches < 5.426 seconds
