Whakaoti i te -214/15-119/45=

$$- 2 \frac { 14 } { 15 } - 1 \frac { 19 } { 45 } =$$

Aromātai

$$-\frac{196}{45}\approx -4.355555556$$

Ngā Upane Otinga

Whakareatia te 2 ki te 15, ka 30.

$$-\frac{30+14}{15}-\frac{1\times 45+19}{45}$$

Tāpirihia te 30 ki te 14, ka 44.

$$-\frac{44}{15}-\frac{1\times 45+19}{45}$$

Whakareatia te 1 ki te 45, ka 45.

$$-\frac{44}{15}-\frac{45+19}{45}$$

Tāpirihia te 45 ki te 19, ka 64.

$$-\frac{44}{15}-\frac{64}{45}$$

Ko te maha noa iti rawa atu o 15 me 45 ko 45. Me tahuri -\frac{44}{15} me \frac{64}{45} ki te hautau me te tautūnga 45.

$$-\frac{132}{45}-\frac{64}{45}$$

Tā te mea he rite te tauraro o -\frac{132}{45} me \frac{64}{45}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{-132-64}{45}$$

Tangohia te 64 i te -132, ka -196.

$$-\frac{196}{45}$$

Tauwehe

$$-\frac{196}{45} = -4\frac{16}{45} = -4.355555555555555$$
