Aromātai

$$\frac{2}{3}\approx 0.666666667$$

Ngā Upane Otinga

Tuhia te 8\times \frac{5}{12} hei hautanga kotahi.

$$4-\frac{8\times 5}{12}$$

Whakareatia te 8 ki te 5, ka 40.

$$4-\frac{40}{12}$$

Whakahekea te hautanga \frac{40}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$4-\frac{10}{3}$$

Me tahuri te 4 ki te hautau \frac{12}{3}.

$$\frac{12}{3}-\frac{10}{3}$$

Tā te mea he rite te tauraro o \frac{12}{3} me \frac{10}{3}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{12-10}{3}$$

Tangohia te 10 i te 12, ka 2.

$$\frac{2}{3}$$

Tauwehe

$$\frac{2}{3} = 0.6666666666666666$$
