Answer 1

\(\dfrac{3}{4}:\dfrac{2}{3}\times\dfrac{8}{9}\)

\(=\dfrac{3}{4}\times\dfrac{3}{2}\times\dfrac{8}{9}\)

\(=\dfrac{3\times3\times8}{4\times2\times9}\)

\(=\dfrac{9\times8}{9\times8}\)

\(=1\)

Answer 2

      \(\dfrac{3}{4}\): \(\dfrac{2}{3}\)x \(\dfrac{8}{9}\) 

=     \(\dfrac{3}{4}\) x \(\dfrac{3}{2}\) x \(\dfrac{8}{9}\)

=      \(\dfrac{9}{8}\) x  \(\dfrac{8}{9}\)

= 1
