Ngā Upane Otinga

Tātaihia te -\frac{5}{2} mā te pū o 3, kia riro ko -\frac{125}{8}.

$$1+\frac{7}{5}\left(-\frac{125}{8}\right)+\frac{2}{\frac{3}{2}}-2\left(\frac{1}{3}-\frac{3}{4}\right)$$

Me whakarea te \frac{7}{5} ki te -\frac{125}{8} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$1+\frac{7\left(-125\right)}{5\times 8}+\frac{2}{\frac{3}{2}}-2\left(\frac{1}{3}-\frac{3}{4}\right)$$

Mahia ngā whakarea i roto i te hautanga \frac{7\left(-125\right)}{5\times 8}.

$$1+\frac{-875}{40}+\frac{2}{\frac{3}{2}}-2\left(\frac{1}{3}-\frac{3}{4}\right)$$

Whakahekea te hautanga \frac{-875}{40} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$1-\frac{175}{8}+\frac{2}{\frac{3}{2}}-2\left(\frac{1}{3}-\frac{3}{4}\right)$$

Me tahuri te 1 ki te hautau \frac{8}{8}.

$$\frac{8}{8}-\frac{175}{8}+\frac{2}{\frac{3}{2}}-2\left(\frac{1}{3}-\frac{3}{4}\right)$$

Tā te mea he rite te tauraro o \frac{8}{8} me \frac{175}{8}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{8-175}{8}+\frac{2}{\frac{3}{2}}-2\left(\frac{1}{3}-\frac{3}{4}\right)$$

Tangohia te 175 i te 8, ka -167.

$$-\frac{167}{8}+\frac{2}{\frac{3}{2}}-2\left(\frac{1}{3}-\frac{3}{4}\right)$$

Whakawehe 2 ki te \frac{3}{2} mā te whakarea 2 ki te tau huripoki o \frac{3}{2}.

$$-\frac{167}{8}+2\times \frac{2}{3}-2\left(\frac{1}{3}-\frac{3}{4}\right)$$

Tuhia te 2\times \frac{2}{3} hei hautanga kotahi.

$$-\frac{167}{8}+\frac{2\times 2}{3}-2\left(\frac{1}{3}-\frac{3}{4}\right)$$

Whakareatia te 2 ki te 2, ka 4.

$$-\frac{167}{8}+\frac{4}{3}-2\left(\frac{1}{3}-\frac{3}{4}\right)$$

Ko te maha noa iti rawa atu o 8 me 3 ko 24. Me tahuri -\frac{167}{8} me \frac{4}{3} ki te hautau me te tautūnga 24.

$$-\frac{501}{24}+\frac{32}{24}-2\left(\frac{1}{3}-\frac{3}{4}\right)$$

Tā te mea he rite te tauraro o -\frac{501}{24} me \frac{32}{24}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-501+32}{24}-2\left(\frac{1}{3}-\frac{3}{4}\right)$$

Tāpirihia te -501 ki te 32, ka -469.

$$-\frac{469}{24}-2\left(\frac{1}{3}-\frac{3}{4}\right)$$

Ko te maha noa iti rawa atu o 3 me 4 ko 12. Me tahuri \frac{1}{3} me \frac{3}{4} ki te hautau me te tautūnga 12.

$$-\frac{469}{24}-2\left(\frac{4}{12}-\frac{9}{12}\right)$$

Tā te mea he rite te tauraro o \frac{4}{12} me \frac{9}{12}, me tango rāua mā te tango i ō raua taurunga.

$$-\frac{469}{24}-2\times \frac{4-9}{12}$$

Tangohia te 9 i te 4, ka -5.

$$-\frac{469}{24}-2\left(-\frac{5}{12}\right)$$

Tuhia te 2\left(-\frac{5}{12}\right) hei hautanga kotahi.

$$-\frac{469}{24}-\frac{2\left(-5\right)}{12}$$

Whakareatia te 2 ki te -5, ka -10.

$$-\frac{469}{24}-\frac{-10}{12}$$

Whakahekea te hautanga \frac{-10}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$-\frac{469}{24}-\left(-\frac{5}{6}\right)$$

Ko te tauaro o -\frac{5}{6} ko \frac{5}{6}.

$$-\frac{469}{24}+\frac{5}{6}$$

Ko te maha noa iti rawa atu o 24 me 6 ko 24. Me tahuri -\frac{469}{24} me \frac{5}{6} ki te hautau me te tautūnga 24.

$$-\frac{469}{24}+\frac{20}{24}$$

Tā te mea he rite te tauraro o -\frac{469}{24} me \frac{20}{24}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-469+20}{24}$$

Tāpirihia te -469 ki te 20, ka -449.

$$-\frac{449}{24}$$

Tauwehe

$$-\frac{449}{24} = -18\frac{17}{24} = -18.708333333333332$$
