Ngā Upane Otinga

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

$$4.32\times \frac{1}{10}-2.5\times 10^{-1}\times 115$$

Whakareatia te 4.32 ki te \frac{1}{10}, ka \frac{54}{125}.

$$\frac{54}{125}-2.5\times 10^{-1}\times 115$$

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

$$\frac{54}{125}-2.5\times \frac{1}{10}\times 115$$

Whakareatia te 2.5 ki te \frac{1}{10}, ka \frac{1}{4}.

$$\frac{54}{125}-\frac{1}{4}\times 115$$

Whakareatia te \frac{1}{4} ki te 115, ka \frac{115}{4}.

$$\frac{54}{125}-\frac{115}{4}$$

Tangohia te \frac{115}{4} i te \frac{54}{125}, ka -\frac{14159}{500}.

$$-\frac{14159}{500}$$
