Ngā Upane Otinga

Whakahekea te hautanga \frac{60}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 20.

$$\frac{72}{1-\frac{3}{5}}$$

Me tahuri te 1 ki te hautau \frac{5}{5}.

$$\frac{72}{\frac{5}{5}-\frac{3}{5}}$$

Tā te mea he rite te tauraro o \frac{5}{5} me \frac{3}{5}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{72}{\frac{5-3}{5}}$$

Tangohia te 3 i te 5, ka 2.

$$\frac{72}{\frac{2}{5}}$$

Whakawehe 72 ki te \frac{2}{5} mā te whakarea 72 ki te tau huripoki o \frac{2}{5}.

$$72\times \frac{5}{2}$$

Tuhia te 72\times \frac{5}{2} hei hautanga kotahi.

$$\frac{72\times 5}{2}$$

Whakareatia te 72 ki te 5, ka 360.

$$\frac{360}{2}$$

Whakawehea te 360 ki te 2, kia riro ko 180.
