We want to know which of the given expressions will produce an answer with three significant figures. That is, it has an answer with three nonzero numbers.

Let us find the values to know

`\begin{gathered} 100-83.4=16.6 \\ \text{YES, IT PRODUCES AN ANSWER WITH THREE SIGNIFICANT FIGURES} \end{gathered}`
`\begin{gathered} (101)/(3.75)=26.9333\ldots \\ \\ \text{IT PRODUCES AN ANSWER WITH MORE THAN THREE SIGNIFICANT FIGURES} \end{gathered}`
`\begin{gathered} 2.45+18.3=20.75 \\ \text{YES, IT PRODUCES AN ANSWER WITH THREE SIGNIFICANT FIGURES} \end{gathered}`
`\begin{gathered} 10*1.5=15 \\ NO\text{, IT DOES NOT PRODUCES AN ANSWER WITH THREE SIGNIFICANT FIGURES} \end{gathered}`
