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

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

Aromātai

$$\frac{x}{4}-\frac{14}{9}$$

Ngā Hipanga Rongoā Poto

Ko te maha noa iti rawa atu o 3 me 9 ko 9. Me tahuri -\frac{7}{3} me \frac{7}{9} ki te hautau me te tautūnga 9.

$$\frac{x}{4}-\frac{21}{9}+\frac{7}{9}$$

Tā te mea he rite te tauraro o -\frac{21}{9} me \frac{7}{9}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{x}{4}+\frac{-21+7}{9}$$

Tāpirihia te -21 ki te 7, ka -14.

$$\frac{x}{4}-\frac{14}{9}$$

Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Ko te taurea pātahi iti rawa o 4 me 9 ko 36. Whakareatia \frac{x}{4} ki te \frac{9}{9}. Whakareatia \frac{14}{9} ki te \frac{4}{4}.

$$\frac{9x}{36}-\frac{14\times 4}{36}$$

Tā te mea he rite te tauraro o \frac{9x}{36} me \frac{14\times 4}{36}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{9x-14\times 4}{36}$$

Mahia ngā whakarea i roto o 9x-14\times 4.

$$\frac{9x-56}{36}$$

Tauwehe

$$\frac{9x-56}{36}$$

Ngā Upane Otinga

Tauwehea te \frac{1}{36}.

$$\frac{9x-56}{36}$$

Whakaarohia te 9x-84+28. Whakarea ka paheko i ngā kīanga tau ōrite.

$$9x-56$$

Me tuhi anō te kīanga whakatauwehe katoa.

$$\frac{9x-56}{36}$$
