Ngā Upane Otinga

Tangohia te 89 i te 80, ka -9.

$$\frac{3\left(-9\right)+6}{76-2-57}+\frac{36}{45}$$

Whakareatia te 3 ki te -9, ka -27.

$$\frac{-27+6}{76-2-57}+\frac{36}{45}$$

Tāpirihia te -27 ki te 6, ka -21.

$$\frac{-21}{76-2-57}+\frac{36}{45}$$

Tangohia te 2 i te 76, ka 74.

$$\frac{-21}{74-57}+\frac{36}{45}$$

Tangohia te 57 i te 74, ka 17.

$$\frac{-21}{17}+\frac{36}{45}$$

Ka taea te hautanga \frac{-21}{17} te tuhi anō ko -\frac{21}{17} mā te tango i te tohu tōraro.

$$-\frac{21}{17}+\frac{36}{45}$$

Whakahekea te hautanga \frac{36}{45} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 9.

$$-\frac{21}{17}+\frac{4}{5}$$

Ko te maha noa iti rawa atu o 17 me 5 ko 85. Me tahuri -\frac{21}{17} me \frac{4}{5} ki te hautau me te tautūnga 85.

$$-\frac{105}{85}+\frac{68}{85}$$

Tā te mea he rite te tauraro o -\frac{105}{85} me \frac{68}{85}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-105+68}{85}$$

Tāpirihia te -105 ki te 68, ka -37.

$$-\frac{37}{85}$$

Tauwehe

$$-\frac{37}{85} = -0.43529411764705883$$
