$$\frac{\left(5\times 8+5\right)\times 7}{8\left(1\times 7+2\right)}$$

Immultiplika 5 u 8 biex tikseb 40.

$$\frac{\left(40+5\right)\times 7}{8\left(1\times 7+2\right)}$$

Żid 40 u 5 biex tikseb 45.

$$\frac{45\times 7}{8\left(1\times 7+2\right)}$$

Immultiplika 45 u 7 biex tikseb 315.

$$\frac{315}{8\left(1\times 7+2\right)}$$

Immultiplika 1 u 7 biex tikseb 7.

$$\frac{315}{8\left(7+2\right)}$$

Żid 7 u 2 biex tikseb 9.

$$\frac{315}{8\times 9}$$

Immultiplika 8 u 9 biex tikseb 72.

$$\frac{315}{72}$$
