[tex]\huge\text{Hey there!}[/tex]

[tex]\huge\textbf{Original equation/problem:}[/tex]

[tex]\mathbf{687\times391}[/tex]

[tex]\mathbf{= 391\times687}[/tex]

[tex]\mathbf{= 268,617}[/tex]

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

[tex]\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.}[/tex]

[tex]\mathbf{687 \rightarrow 700}\\\mathbf{391\rightarrow 400}[/tex]

[tex]\huge\textbf{New equation:}[/tex]

[tex]\mathbf{700 \times 400}[/tex]

[tex]\mathbf{= 400\times700}[/tex]

[tex]\mathbf{= 280,000}[/tex]

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

[tex]\huge\text{Good luck on your assignment \& enjoy your day!}[/tex]
