What will come in place of the question mark (?) in the given questions?
$$\frac{2}{3}-\frac{5}{7}$$ of $$\frac{21}{23}$$ of $$\frac{46}{51} = ?$$ of $$\frac{8}{85}$$
Expression : $$\frac{2}{3}-\frac{5}{7}$$ of $$\frac{21}{23}$$ of $$\frac{46}{51} = ?$$ of $$\frac{8}{85}$$
=> $$\frac{2}{3} - (\frac{5}{7} \times \frac{21}{23} \times \frac{46}{51}) = x \times \frac{8}{85}$$
=> $$\frac{2}{3} - \frac{10}{17} = \frac{8x}{85}$$
=> $$\frac{4}{51} = \frac{8x}{85}$$
=> $$x = \frac{4 \times 85}{51 \times 8}$$
=> $$x = \frac{5}{6}$$
