$\frac{3}{4}$ $\times$ $\frac{8}{9}$ $\times$ $\frac{12}{20}$ = $\frac{2}{5}$

Work Step by Step

$\frac{3}{4}$ $\times$ $\frac{8}{9}$ $\times$ $\frac{12}{20}$ = Multiply the numerators by each other, and multiply the denominators by each other $\frac{3\ \times\ 8\ \times\ 12}{4\ \times\ 9\ \times\ 20}$ = Factor the numerator and the denominator $\frac{3\ \times\ 2\ \times\ 2\ \times\ 2\ \times\ 2\ \times\ 2\ \times 3}{2\times2\times3\times3\times2\times2\times5}$ = Cancel the common factors between the numerator and the denominator to obtain: $\frac{2}{5}$
