If (2a + 3b)(2c - 3d) = (2a - 3b)(2c + 3d), then:
\(\frac{a}{b} = \frac{d}{c}\)
\(\frac{a}{b} = \frac{c}{d}\)
\(\frac{a}{d} = \frac{c}{b}\)
\(\frac{b}{a} = \frac{c}{d}\)
16 \(\frac{1}{4} \div \left[2\frac{1}{6} + \left\{4\frac{1}{3} - \left(2\frac{1}{2} + \frac{3}{4}\right)\right\}\right]\) is equal to:
