Which expression has the fewest significant figures? a. 296.54 b. 5003.1 c. 360.01 d. 18.3

Hello!

Here are some rules to determine the number of significant figures.

Now, let's find the number of significant figures in each given number.

A). 296.54

Since these digits are all non-zero, there are 5 significant figures.

B). 5003.1

Since the two zeros are between non-zero digits, they are significant figures. Thus, there are 5 significant figures.

C). 360.01

Again, the two zeros are between non-zero digits. There are 5 significant figures.

D). 18.3

All of these digits are non-zero, hence, there are 3 significant figures.

Therefore, expression D has the fewest number of significant figures being 3.
