Ngā Upane Otinga

Tātaihia te 10 mā te pū o -11, kia riro ko \frac{1}{100000000000}.

$$667\times \frac{1}{100000000000}\times 200000\times 400000$$

Whakareatia te 667 ki te \frac{1}{100000000000}, ka \frac{667}{100000000000}.

$$\frac{667}{100000000000}\times 200000\times 400000$$

Whakareatia te \frac{667}{100000000000} ki te 200000, ka \frac{667}{500000}.

$$\frac{667}{500000}\times 400000$$

Whakareatia te \frac{667}{500000} ki te 400000, ka \frac{2668}{5}.

$$\frac{2668}{5}$$

Tauwehe

$$\frac{2 ^ {2} \cdot 23 \cdot 29}{5} = 533\frac{3}{5} = 533.6$$
