$$11\frac{2}{5}\bullet\frac{4}{9}\div\frac{6}{45}-5$$
$33$
$$\frac{\frac{55+2}{5}\times \frac{4}{9}}{\frac{6}{45}}-5$$
$$\frac{\frac{57}{5}\times \frac{4}{9}}{\frac{6}{45}}-5$$
$$\frac{\frac{57\times 4}{5\times 9}}{\frac{6}{45}}-5$$
$$\frac{\frac{228}{45}}{\frac{6}{45}}-5$$
$$\frac{\frac{76}{15}}{\frac{6}{45}}-5$$
$$\frac{\frac{76}{15}}{\frac{2}{15}}-5$$
$$\frac{76}{15}\times \frac{15}{2}-5$$
$$\frac{76\times 15}{15\times 2}-5$$
$$\frac{76}{2}-5$$
$$38-5$$
$$33$$
