$$1950$$

Ngā Upane Otinga

Whakareatia te \frac{1}{4} ki te 314, ka \frac{314}{4}.

$$\frac{314}{4}\times 25-\frac{1}{2}\times 5\times 5$$

Whakahekea te hautanga \frac{314}{4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{157}{2}\times 25-\frac{1}{2}\times 5\times 5$$

Tuhia te \frac{157}{2}\times 25 hei hautanga kotahi.

$$\frac{157\times 25}{2}-\frac{1}{2}\times 5\times 5$$

Whakareatia te 157 ki te 25, ka 3925.

$$\frac{3925}{2}-\frac{1}{2}\times 5\times 5$$

Whakareatia te \frac{1}{2} ki te 5, ka \frac{5}{2}.

$$\frac{3925}{2}-\frac{5}{2}\times 5$$

Tuhia te \frac{5}{2}\times 5 hei hautanga kotahi.

$$\frac{3925}{2}-\frac{5\times 5}{2}$$

Whakareatia te 5 ki te 5, ka 25.

$$\frac{3925}{2}-\frac{25}{2}$$

Tā te mea he rite te tauraro o \frac{3925}{2} me \frac{25}{2}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{3925-25}{2}$$

Tangohia te 25 i te 3925, ka 3900.

$$\frac{3900}{2}$$

Whakawehea te 3900 ki te 2, kia riro ko 1950.

$$1950$$
