Question

What is number of significant figures in $0.310\times 103$ ?

• A. 2
• B. 3
• C. 4
• D. 6

Answer 1

Answer: (B)

3

Since the numbers $0.310$ and $103$ have 3 significant figures each. In the case of the multiplication, the maximum number of significant figures is the same as that of the number of significant figures in decimal number., so the final answer must also have 3 significant figures.
