Question

How many significant figures will there be inthe answer to the following problem? `101.7 * 5.45`

Answer 1

There will be three significant figures in the answer.

Explanation:

When multiplying or dividing measurements (numbers), the result must have the same number of significant figures as the number in the problem with the fewest significant figures.

`101.7xx5.45=554.265` on the calculator. However, you would record the result as `554` because `5.45` has the least significant figures, so the result must be rounded to three significant figures.
