Whakaoti i te -31/7-23/4

$$- 3 \frac { 1 } { 7 } - 2 \frac { 3 } { 4 }$$

Aromātai

$$-\frac{165}{28}\approx -5.892857143$$

Ngā Upane Otinga

Whakareatia te 3 ki te 7, ka 21.

$$-\frac{21+1}{7}-\frac{2\times 4+3}{4}$$

Tāpirihia te 21 ki te 1, ka 22.

$$-\frac{22}{7}-\frac{2\times 4+3}{4}$$

Whakareatia te 2 ki te 4, ka 8.

$$-\frac{22}{7}-\frac{8+3}{4}$$

Tāpirihia te 8 ki te 3, ka 11.

$$-\frac{22}{7}-\frac{11}{4}$$

Ko te maha noa iti rawa atu o 7 me 4 ko 28. Me tahuri -\frac{22}{7} me \frac{11}{4} ki te hautau me te tautūnga 28.

$$-\frac{88}{28}-\frac{77}{28}$$

Tā te mea he rite te tauraro o -\frac{88}{28} me \frac{77}{28}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{-88-77}{28}$$

Tangohia te 77 i te -88, ka -165.

$$-\frac{165}{28}$$

Tauwehe

$$-\frac{165}{28} = -5\frac{25}{28} = -5.892857142857143$$
