\huge\text{Hey there!}


\huge\textbf{Original equation/problem:}


\mathbf{687*391}


\mathbf{= 391*687}


\mathbf{= 268,617}


\huge\textbf{Now, we're going to solve for your}\\\huge\textbf{question:}


\huge\text{Assuming you want us to estimate to the}\\\huge\text{nearest hundred. So we will do so, because}\\\huge\text{it is easier to understand it like that.}


\mathbf{687 \rightarrow 700}\\\mathbf{391\rightarrow 400}


\huge\textbf{New equation:}


\mathbf{700 * 400}


\mathbf{= 400*700}


\mathbf{= 280,000}


\huge\text{Therefore, your answer is: \boxed{\mathsf{Option\ A.\ 280,000}}}\huge\checkmark


\huge\text{Good luck on your assignment \& enjoy your day!}
