Four students measure the mass of an object, each using a different scale. They record their results as follows:
Student A B C D
Mass (g)49.06 49 50 49.1
E
49.061
Which student used the most precise scale?
Student E used the most precise scale; this can be seen by the number of digits after the decimal.
49.061
To determine which student used the most precise scale, we need to compare the decimal places of their measurements.
Student A: 49.06 (2 decimal places)
Student B: 49 (0 decimal places)
Student C: 50 (0 decimal places)
Student D: 49.1 (1 decimal place)
Student E: 49.061 (3 decimal places)
Based on the number of decimal places, Student E used the most precise scale with a measurement of 49.061.
To determine which student used the most precise scale, we need to compare the measurement with the smallest decimal places. The student with the measurement that has the most decimal places is using the most precise scale.
Let's compare the measurements:
Student A: 49.06 (2 decimal places)
Student B: 49 (0 decimal places)
Student C: 50 (0 decimal places)
Student D: 49.1 (1 decimal place)
Student E: 49.061 (3 decimal places)
From the comparisons, we can see that Student E used the most precise scale. The measurement of 49.061 has the most decimal places, indicating a higher level of precision in the measurement.
