Ngā Upane Otinga

Tangohia te 14 i te 12915, ka 12901.

$$405+\frac{12901}{14}\times 5$$

Whakahekea te hautanga \frac{12901}{14} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 7.

$$405+\frac{1843}{2}\times 5$$

$$405+\frac{9215}{2}$$

Me tahuri te 405 ki te hautau \frac{810}{2}.

$$\frac{810}{2}+\frac{9215}{2}$$

Tā te mea he rite te tauraro o \frac{810}{2} me \frac{9215}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{810+9215}{2}$$

Tāpirihia te 810 ki te 9215, ka 10025.

$$\frac{10025}{2}$$

Tauwehe
