Ngā Upane Otinga

Whakareatia te 5 ki te 4, ka 20.

$$1.5+\frac{\frac{20+1}{4}}{-\frac{3\times 2+1}{2}}$$

Tāpirihia te 20 ki te 1, ka 21.

$$1.5+\frac{\frac{21}{4}}{-\frac{3\times 2+1}{2}}$$

Whakareatia te 3 ki te 2, ka 6.

$$1.5+\frac{\frac{21}{4}}{-\frac{6+1}{2}}$$

Tāpirihia te 6 ki te 1, ka 7.

$$1.5+\frac{\frac{21}{4}}{-\frac{7}{2}}$$

Whakawehe \frac{21}{4} ki te -\frac{7}{2} mā te whakarea \frac{21}{4} ki te tau huripoki o -\frac{7}{2}.

$$1.5+\frac{21}{4}\left(-\frac{2}{7}\right)$$

Me whakarea te \frac{21}{4} ki te -\frac{2}{7} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$1.5+\frac{21\left(-2\right)}{4\times 7}$$

Mahia ngā whakarea i roto i te hautanga \frac{21\left(-2\right)}{4\times 7}.

$$1.5+\frac{-42}{28}$$

Whakahekea te hautanga \frac{-42}{28} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 14.

$$1.5-\frac{3}{2}$$
