Ngā Upane Otinga

Me tahuri te 1 ki te hautau \frac{7}{7}.

$$\left(\frac{3}{7}-\frac{7}{7}\right)\left(1.6+3\right)$$

Tā te mea he rite te tauraro o \frac{3}{7} me \frac{7}{7}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{3-7}{7}\left(1.6+3\right)$$

Tangohia te 7 i te 3, ka -4.

$$-\frac{4}{7}\left(1.6+3\right)$$

Tāpirihia te 1.6 ki te 3, ka 4.6.

$$-\frac{4}{7}\times 4.6$$

Me tahuri ki tau ā-ira 4.6 ki te hautau \frac{46}{10}. Whakahekea te hautanga \frac{46}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$-\frac{4}{7}\times \frac{23}{5}$$

Me whakarea te -\frac{4}{7} ki te \frac{23}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{-4\times 23}{7\times 5}$$

Mahia ngā whakarea i roto i te hautanga \frac{-4\times 23}{7\times 5}.

$$\frac{-92}{35}$$

Ka taea te hautanga \frac{-92}{35} te tuhi anō ko -\frac{92}{35} mā te tango i te tohu tōraro.

$$-\frac{92}{35}$$

Tauwehe

$$-\frac{92}{35} = -2\frac{22}{35} = -2.6285714285714286$$
