Ngā Upane Otinga

Whakareatia te 5 ki te 0.125, ka 0.625.

$$0.625\times 3.7\left(-\frac{4}{7}\right)\left(-\frac{1\times 4+3}{4}\right)\left(-80\right)$$

Whakareatia te 0.625 ki te 3.7, ka 2.3125.

$$2.3125\left(-\frac{4}{7}\right)\left(-\frac{1\times 4+3}{4}\right)\left(-80\right)$$

Me tahuri ki tau ā-ira 2.3125 ki te hautau \frac{23125}{10000}. Whakahekea te hautanga \frac{23125}{10000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 625.

$$\frac{37}{16}\left(-\frac{4}{7}\right)\left(-\frac{1\times 4+3}{4}\right)\left(-80\right)$$

Me whakarea te \frac{37}{16} ki te -\frac{4}{7} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{37\left(-4\right)}{16\times 7}\left(-\frac{1\times 4+3}{4}\right)\left(-80\right)$$

Mahia ngā whakarea i roto i te hautanga \frac{37\left(-4\right)}{16\times 7}.

$$\frac{-148}{112}\left(-\frac{1\times 4+3}{4}\right)\left(-80\right)$$

Whakahekea te hautanga \frac{-148}{112} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$-\frac{37}{28}\left(-\frac{4+3}{4}\right)\left(-80\right)$$

Tāpirihia te 4 ki te 3, ka 7.

$$-\frac{37}{28}\left(-\frac{7}{4}\right)\left(-80\right)$$

Me whakarea te -\frac{37}{28} ki te -\frac{7}{4} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{-37\left(-7\right)}{28\times 4}\left(-80\right)$$

Mahia ngā whakarea i roto i te hautanga \frac{-37\left(-7\right)}{28\times 4}.

$$\frac{259}{112}\left(-80\right)$$

Whakahekea te hautanga \frac{259}{112} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 7.

$$\frac{37}{16}\left(-80\right)$$

Tuhia te \frac{37}{16}\left(-80\right) hei hautanga kotahi.

$$\frac{37\left(-80\right)}{16}$$

Whakareatia te 37 ki te -80, ka -2960.

$$\frac{-2960}{16}$$

Whakawehea te -2960 ki te 16, kia riro ko -185.
