Ngā Upane Otinga

Tātaihia te 30 mā te pū o 2, kia riro ko 900.

$$\frac{900}{6}\left(2\times 0.08+0.52+2\times 0.39-0.05\right)$$

Whakawehea te 900 ki te 6, kia riro ko 150.

$$150\left(2\times 0.08+0.52+2\times 0.39-0.05\right)$$

Whakareatia te 2 ki te 0.08, ka 0.16.

$$150\left(0.16+0.52+2\times 0.39-0.05\right)$$

Tāpirihia te 0.16 ki te 0.52, ka 0.68.

$$150\left(0.68+2\times 0.39-0.05\right)$$

Whakareatia te 2 ki te 0.39, ka 0.78.

$$150\left(0.68+0.78-0.05\right)$$

Tāpirihia te 0.68 ki te 0.78, ka 1.46.

$$150\left(1.46-0.05\right)$$

Tangohia te 0.05 i te 1.46, ka 1.41.

$$150\times 1.41$$

Whakareatia te 150 ki te 1.41, ka 211.5.

$$211.5$$

Tauwehe

$$\frac{47 \cdot 3 ^ {2}}{2} = 211\frac{1}{2} = 211.5$$
