Answer 4

\(\frac{321}{325}\times\frac{322}{324}\times\frac{323}{321}\times\frac{325}{323}\)

\(=(\frac{321}{325}\times(\frac{323}{321}\times\frac{325}{323}))\times\frac{322}{324}\)

\(=\left(\frac{321}{325}\times\frac{325}{321}\right)\times\frac{322}{324}\)

\(=\frac{1}{1}\times\frac{322}{324}\)

\(=\frac{322}{324}\)

\(=\frac{161}{162}\)
