What is the measurement of 417.32 g when rounded to four significant figures?

Answer 1

Peyton Adams

To four significant figures, the measurement is 417.3 g.

All five of the digits are important because none of them are zero.

The first question you should ask yourself when rounding a number is: to what?

You are counting from the left and rounding to four significant figures in this problem.

You are rounding to the closest tenth after reaching the "3" as a result.

One piece of advice: just focus on the number in the location you are rounding to and the number that comes after it.

You only need to focus on the number "3" and the number "2" that comes after it in this problem.
