Evaluate: 2^3

Expression: $\frac{2}{7}\div \frac{3}{4}$

Apply the fraction rule $\frac{a}{b}\div\frac{c}{d}=\frac{a}{b}\times\frac{d}{c}$

$=\frac{2}{7}\times \frac{4}{3}$

Multiply fractions $\frac{a}{b}\times\frac{c}{d}=\frac{a \times c}{b \times d}$

$=\frac{2\times 4}{7\times 3}$

Multiply the numbers: $ 2\times 4=8$

$=\frac{8}{7\times 3}$

Multiply the numbers: $ 7\times 3=21$

$=\frac{8}{21}$
