$$\frac{10}{3}\approx 3.333333333$$

Ngā Upane Otinga

Tangohia te 5 i te 7, ka 2.

$$2+\frac{3}{9}\times 4$$

Whakahekea te hautanga \frac{3}{9} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$2+\frac{1}{3}\times 4$$

Whakareatia te \frac{1}{3} ki te 4, ka \frac{4}{3}.

$$2+\frac{4}{3}$$

Me tahuri te 2 ki te hautau \frac{6}{3}.

$$\frac{6}{3}+\frac{4}{3}$$

Tā te mea he rite te tauraro o \frac{6}{3} me \frac{4}{3}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{6+4}{3}$$

Tāpirihia te 6 ki te 4, ka 10.

$$\frac{10}{3}$$

Tauwehe

$$\frac{2 \cdot 5}{3} = 3\frac{1}{3} = 3.3333333333333335$$
