Whakaoti i te 7/9+8/4-8/3

$$\frac{ 7 }{ 9 } + \frac{ 8 }{ 4 } - \frac{ 8 }{ 3 }$$

Aromātai

$$\frac{1}{9}\approx 0.111111111$$

Ngā Upane Otinga

Whakawehea te 8 ki te 4, kia riro ko 2.

$$\frac{7}{9}+2-\frac{8}{3}$$

Me tahuri te 2 ki te hautau \frac{18}{9}.

$$\frac{7}{9}+\frac{18}{9}-\frac{8}{3}$$

Tā te mea he rite te tauraro o \frac{7}{9} me \frac{18}{9}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{7+18}{9}-\frac{8}{3}$$

Tāpirihia te 7 ki te 18, ka 25.

$$\frac{25}{9}-\frac{8}{3}$$

Ko te maha noa iti rawa atu o 9 me 3 ko 9. Me tahuri \frac{25}{9} me \frac{8}{3} ki te hautau me te tautūnga 9.

$$\frac{25}{9}-\frac{24}{9}$$

Tā te mea he rite te tauraro o \frac{25}{9} me \frac{24}{9}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{25-24}{9}$$

Tangohia te 24 i te 25, ka 1.

$$\frac{1}{9}$$

Tauwehe

$$\frac{1}{3 ^ {2}} = 0.1111111111111111$$
