tolong ini caranya bagaimana ya?

[tex] \frac{ \frac{x}{y} - \frac{y}{x} }{ \frac{2x}{y} - \frac{2y}{x} } \\ = \frac{ \frac{x ^{2} - y ^{2} }{xy} }{ \frac{2x ^{2} - 2y ^{2} }{xy} } \\ = \frac{x ^{2} - y ^{2} }{xy} \div \frac{2x ^{2} - 2y ^{2} }{xy} \\ = \frac{x ^{2} - y^{2} }{xy} \times \frac{xy}{2x ^{2} - 2y ^{2} } \\ = \frac{1}{1} \times \frac{1}{2} \\ = \frac{1}{2} [/tex]
Jawaban : a. ½

Maaf Kalau Salah

x/y-y/x / 2x/y-2y/x
= x^2-y^2/xy /2x^2-2y^2/xy
= x^2-y^2/xy : 2x^2-2y^2/xy
= x^2-y^2/xy × xy/2x^2-2y^2
= 1/1 × 1/2
= 1/2 ------ A

JADIKAN JAWABAN TERBAIK YA semoga membantu
