Ngā Upane Otinga

Whakareatia te 4 ki te 3, ka 12. Whakareatia te 4 ki te 5, ka 20. Whakareatia te 5 ki te 4, ka 20.

$$\frac{12\times 7+20\times 6\times 2+20\times 5}{9\times 8\left(4+5+2\right)}$$

Whakareatia te 12 ki te 7, ka 84.

$$\frac{84+20\times 6\times 2+20\times 5}{9\times 8\left(4+5+2\right)}$$

Whakareatia te 20 ki te 6, ka 120.

$$\frac{84+120\times 2+20\times 5}{9\times 8\left(4+5+2\right)}$$

Whakareatia te 120 ki te 2, ka 240.

$$\frac{84+240+20\times 5}{9\times 8\left(4+5+2\right)}$$

Tāpirihia te 84 ki te 240, ka 324.

$$\frac{324+20\times 5}{9\times 8\left(4+5+2\right)}$$

Whakareatia te 20 ki te 5, ka 100.

$$\frac{324+100}{9\times 8\left(4+5+2\right)}$$
