There will be three significant figures in the answer.


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.
