Ngā Upane Otinga

Tuhia te \frac{3}{50}\times 10 hei hautanga kotahi.

$$65.5+\frac{3\times 10}{50}$$

Whakareatia te 3 ki te 10, ka 30.

$$65.5+\frac{30}{50}$$

Whakahekea te hautanga \frac{30}{50} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 10.

$$65.5+\frac{3}{5}$$

Me tahuri ki tau ā-ira 65.5 ki te hautau \frac{655}{10}. Whakahekea te hautanga \frac{655}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$\frac{131}{2}+\frac{3}{5}$$

Ko te maha noa iti rawa atu o 2 me 5 ko 10. Me tahuri \frac{131}{2} me \frac{3}{5} ki te hautau me te tautūnga 10.

$$\frac{655}{10}+\frac{6}{10}$$

Tā te mea he rite te tauraro o \frac{655}{10} me \frac{6}{10}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{655+6}{10}$$

Tāpirihia te 655 ki te 6, ka 661.

$$\frac{661}{10}$$

Tauwehe

$$\frac{661}{2 \cdot 5} = 66\frac{1}{10} = 66.1$$
