Whakaoti i te (-21/4)+(-7/12)

$$( - 2 \frac { 1 } { 4 } ) + ( - \frac { 7 } { 12 } )$$

Aromātai

$$-\frac{17}{6}\approx -2.833333333$$

Ngā Upane Otinga

Whakareatia te 2 ki te 4, ka 8.

$$-\frac{8+1}{4}-\frac{7}{12}$$

Tāpirihia te 8 ki te 1, ka 9.

$$-\frac{9}{4}-\frac{7}{12}$$

Ko te maha noa iti rawa atu o 4 me 12 ko 12. Me tahuri -\frac{9}{4} me \frac{7}{12} ki te hautau me te tautūnga 12.

$$-\frac{27}{12}-\frac{7}{12}$$

Tā te mea he rite te tauraro o -\frac{27}{12} me \frac{7}{12}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{-27-7}{12}$$

Tangohia te 7 i te -27, ka -34.

$$\frac{-34}{12}$$

Whakahekea te hautanga \frac{-34}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$-\frac{17}{6}$$

Tauwehe

$$-\frac{17}{6} = -2\frac{5}{6} = -2.8333333333333335$$
