Answer:

The simplest form of the complex fraction $\frac{\frac{8}{9}}{8}$ is $\frac{1}{9}$

Step-by-step explanation:

In the complex fractions $\frac{\frac{a}{b}}{c}$ = $\frac{a}{b}$ ÷ c

To simplify it change ÷ to × and reciprocal c

$\frac{\frac{a}{b}}{c}$ = $\frac{a}{b}$ ÷ c = $\frac{a}{b}$ × $\frac{1}{c}$ = $\frac{a}{bc}$

In the complex fractions $\frac{a}{\frac{b}{c}}$ = a ÷ $\frac{b}{c}$

To simplify it change ÷ to × and reciprocal $\frac{b}{c}$

$\frac{a}{\frac{b}{c}}$ = a ÷ $\frac{b}{c}$ = a × $\frac{c}{b}$ = $\frac{ac}{b}$

Let us solve the question

∵ The complex fraction is $\frac{\frac{8}{9}}{8}$

∵ $\frac{\frac{8}{9}}{8}$ = $\frac{8}{9}$ ÷ 8

→ Change ÷ to × and reciprocal 8

∴ $\frac{8}{9}$ ÷ 8 = $\frac{8}{9}$ × $\frac{1}{8}$

→ Cancel 8 up with 8 down

∴ $\frac{8}{9}$ × $\frac{1}{8}$ = $\frac{1}{9}$

∴ The simplest form of the complex fraction $\frac{\frac{8}{9}}{8}$ is $\frac{1}{9}$
