Given that \(|\frac{a}{c} \frac{b}{d}|=ad-bc\) and we need to find the value of \(|\frac{3}{-2} \frac{5}{4}|\)
Comparing \(|\frac{3}{-2} \frac{5}{4}|\) and \(|\frac{a}{c} \frac{b}{d}|\) we get
a = 3, b = 5, c = -2, d = 4
=> \(|\frac{3}{-2} \frac{5}{4}|=3*4 - 5*-2\) = 12 + 10 = 22
So, Answer will be E
Hope it helps!
