Ngā Upane Otinga

Whakareatia te 1 ki te 3, ka 3.

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

Tāpirihia te 3 ki te 2, ka 5.

$$\frac{\frac{1}{2}\times \frac{-\frac{5}{3}}{3}}{\frac{3}{4}}$$

Tuhia te \frac{-\frac{5}{3}}{3} hei hautanga kotahi.

$$\frac{\frac{1}{2}\times \frac{-5}{3\times 3}}{\frac{3}{4}}$$

Whakareatia te 3 ki te 3, ka 9.

$$\frac{\frac{1}{2}\times \frac{-5}{9}}{\frac{3}{4}}$$

Ka taea te hautanga \frac{-5}{9} te tuhi anō ko -\frac{5}{9} mā te tango i te tohu tōraro.

$$\frac{\frac{1}{2}\left(-\frac{5}{9}\right)}{\frac{3}{4}}$$

Me whakarea te \frac{1}{2} ki te -\frac{5}{9} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{\frac{1\left(-5\right)}{2\times 9}}{\frac{3}{4}}$$

Mahia ngā whakarea i roto i te hautanga \frac{1\left(-5\right)}{2\times 9}.

$$\frac{\frac{-5}{18}}{\frac{3}{4}}$$

Ka taea te hautanga \frac{-5}{18} te tuhi anō ko -\frac{5}{18} mā te tango i te tohu tōraro.

$$\frac{-\frac{5}{18}}{\frac{3}{4}}$$

Whakawehe -\frac{5}{18} ki te \frac{3}{4} mā te whakarea -\frac{5}{18} ki te tau huripoki o \frac{3}{4}.

$$-\frac{5}{18}\times \frac{4}{3}$$

Me whakarea te -\frac{5}{18} ki te \frac{4}{3} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{-5\times 4}{18\times 3}$$

Mahia ngā whakarea i roto i te hautanga \frac{-5\times 4}{18\times 3}.

$$\frac{-20}{54}$$

Whakahekea te hautanga \frac{-20}{54} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$-\frac{10}{27}$$

Tauwehe

$$-\frac{10}{27} = -0.37037037037037035$$
