Whakaoti i te 1/5--1/9+-5/9-02

$$\frac{ 1 }{ 5 } -- \frac{ 1 }{ 9 } +- \frac{ 5 }{ 9 } -02$$

Aromātai

$$-\frac{11}{45}\approx -0.244444444$$

Ngā Upane Otinga

Ko te tauaro o -\frac{1}{9} ko \frac{1}{9}.

$$\frac{1}{5}+\frac{1}{9}-\frac{5}{9}-0\times 2$$

Ko te maha noa iti rawa atu o 5 me 9 ko 45. Me tahuri \frac{1}{5} me \frac{1}{9} ki te hautau me te tautūnga 45.

$$\frac{9}{45}+\frac{5}{45}-\frac{5}{9}-0\times 2$$

Tā te mea he rite te tauraro o \frac{9}{45} me \frac{5}{45}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{9+5}{45}-\frac{5}{9}-0\times 2$$

Tāpirihia te 9 ki te 5, ka 14.

$$\frac{14}{45}-\frac{5}{9}-0\times 2$$

Ko te maha noa iti rawa atu o 45 me 9 ko 45. Me tahuri \frac{14}{45} me \frac{5}{9} ki te hautau me te tautūnga 45.

$$\frac{14}{45}-\frac{25}{45}-0\times 2$$

Tā te mea he rite te tauraro o \frac{14}{45} me \frac{25}{45}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{14-25}{45}-0\times 2$$

Tangohia te 25 i te 14, ka -11.

$$-\frac{11}{45}-0\times 2$$

Whakareatia te 0 ki te 2, ka 0.

$$-\frac{11}{45}-0$$

Tangohia te 0 i te -\frac{11}{45}, ka -\frac{11}{45}.

$$-\frac{11}{45}$$

Tauwehe

$$-\frac{11}{45} = -0.24444444444444444$$
