Which of the following numbers has the least number of significant figures?
Correct Answer: 100
Step 1: Understand what significant figures are. Significant figures are the digits in a number that carry meaning contributing to its precision.
Step 2: Identify the numbers you are comparing. For example, let's say the numbers are 100, 0.005, and 2500.
Step 3: Count the significant figures in each number. For 100, it has 1 significant figure (the '1'). For 0.005, it has 1 significant figure (the '5'). For 2500, it has 2 significant figures (the '2' and '5').
Step 4: Compare the counts of significant figures. 100 has 1, 0.005 has 1, and 2500 has 2.
Step 5: Determine which number has the least significant figures. Both 100 and 0.005 have the least at 1 significant figure.
