$$-3.5$$

Ngā Upane Otinga

Whakareatia te 4 ki te 6, ka 24.

$$-\frac{24+1}{6}-\frac{\frac{0.7+2.8}{9}}{-\frac{7}{12}}$$

Tāpirihia te 24 ki te 1, ka 25.

$$-\frac{25}{6}-\frac{\frac{0.7+2.8}{9}}{-\frac{7}{12}}$$

Whakawehe \frac{0.7+2.8}{9} ki te -\frac{7}{12} mā te whakarea \frac{0.7+2.8}{9} ki te tau huripoki o -\frac{7}{12}.

$$-\frac{25}{6}-\frac{\left(0.7+2.8\right)\times 12}{9\left(-7\right)}$$

Me whakakore tahi te 3 i te taurunga me te tauraro.

$$-\frac{25}{6}-\frac{4\left(0.7+2.8\right)}{-7\times 3}$$

Tāpirihia te 0.7 ki te 2.8, ka 3.5.

$$-\frac{25}{6}-\frac{4\times 3.5}{-7\times 3}$$

Whakareatia te 4 ki te 3.5, ka 14.

$$-\frac{25}{6}-\frac{14}{-7\times 3}$$

Whakareatia te -7 ki te 3, ka -21.

$$-\frac{25}{6}-\frac{14}{-21}$$

Whakahekea te hautanga \frac{14}{-21} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 7.

$$-\frac{25}{6}-\left(-\frac{2}{3}\right)$$

Ko te tauaro o -\frac{2}{3} ko \frac{2}{3}.

$$-\frac{25}{6}+\frac{2}{3}$$

Ko te maha noa iti rawa atu o 6 me 3 ko 6. Me tahuri -\frac{25}{6} me \frac{2}{3} ki te hautau me te tautūnga 6.

$$-\frac{25}{6}+\frac{4}{6}$$

Tā te mea he rite te tauraro o -\frac{25}{6} me \frac{4}{6}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-25+4}{6}$$

Tāpirihia te -25 ki te 4, ka -21.

$$\frac{-21}{6}$$

Whakahekea te hautanga \frac{-21}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$-\frac{7}{2}$$

Tauwehe

$$-3.5$$
