Whakaoti i te n7/2+9/6+8/9?

$$n \frac { 7 } { 2 } + \frac { 9 } { 6 } + \frac { 8 } { 9 } ?$$

Aromātai

$$\frac{7n}{2}+\frac{43}{18}$$

Ngā Upane Otinga

Whakahekea te hautanga \frac{9}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$n\times \frac{7}{2}+\frac{3}{2}+\frac{8}{9}$$

Ko te maha noa iti rawa atu o 2 me 9 ko 18. Me tahuri \frac{3}{2} me \frac{8}{9} ki te hautau me te tautūnga 18.

$$n\times \frac{7}{2}+\frac{27}{18}+\frac{16}{18}$$

Tā te mea he rite te tauraro o \frac{27}{18} me \frac{16}{18}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$n\times \frac{7}{2}+\frac{27+16}{18}$$

Tāpirihia te 27 ki te 16, ka 43.

$$n\times \frac{7}{2}+\frac{43}{18}$$

Tauwehe

$$\frac{63n+43}{18}$$

Ngā Upane Otinga

Tauwehea te \frac{1}{18}.

$$\frac{63n+43}{18}$$

Whakaarohia te 63n+27+16. Whakarea ka paheko i ngā kīanga tau ōrite.

$$63n+43$$

Me tuhi anō te kīanga whakatauwehe katoa.

$$\frac{63n+43}{18}$$
