Ngā Upane Otinga

Whakawehe \frac{1}{2} ki te \frac{3\times 4+1}{4} mā te whakarea \frac{1}{2} ki te tau huripoki o \frac{3\times 4+1}{4}.

$$|\frac{\frac{4}{2\left(3\times 4+1\right)}}{1}|$$

Whakareatia te 3 ki te 4, ka 12.

$$|\frac{\frac{4}{2\left(12+1\right)}}{1}|$$

Tāpirihia te 12 ki te 1, ka 13.

$$|\frac{\frac{4}{2\times 13}}{1}|$$

Whakareatia te 2 ki te 13, ka 26.

$$|\frac{\frac{4}{26}}{1}|$$

Whakahekea te hautanga \frac{4}{26} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$|\frac{\frac{2}{13}}{1}|$$

Ka whakawehea he tau ki te tahi, hua ai ko ia anō.

$$|\frac{2}{13}|$$

Ko te uara pū o tētahi tau tūturu a ko a ina a\geq 0, ko -a rānei ina a<0. Ko te uara pū o \frac{2}{13} ko \frac{2}{13}.
