Ngā Upane Otinga

Whakarohaina te \frac{7.5}{9.9} mā te whakarea i te taurunga me te tauraro ki te 10.

$$-9.6\left(\frac{75}{99}-4.5\right)$$

Whakahekea te hautanga \frac{75}{99} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$-9.6\left(\frac{25}{33}-4.5\right)$$

Me tahuri ki tau ā-ira 4.5 ki te hautau \frac{45}{10}. Whakahekea te hautanga \frac{45}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$-9.6\left(\frac{25}{33}-\frac{9}{2}\right)$$

Ko te maha noa iti rawa atu o 33 me 2 ko 66. Me tahuri \frac{25}{33} me \frac{9}{2} ki te hautau me te tautūnga 66.

$$-9.6\left(\frac{50}{66}-\frac{297}{66}\right)$$

Tā te mea he rite te tauraro o \frac{50}{66} me \frac{297}{66}, me tango rāua mā te tango i ō raua taurunga.

$$-9.6\times \frac{50-297}{66}$$

Tangohia te 297 i te 50, ka -247.

$$-9.6\left(-\frac{247}{66}\right)$$

Me tahuri ki tau ā-ira -9.6 ki te hautau -\frac{96}{10}. Whakahekea te hautanga -\frac{96}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$-\frac{48}{5}\left(-\frac{247}{66}\right)$$

Me whakarea te -\frac{48}{5} ki te -\frac{247}{66} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{-48\left(-247\right)}{5\times 66}$$

Mahia ngā whakarea i roto i te hautanga \frac{-48\left(-247\right)}{5\times 66}.

$$\frac{11856}{330}$$

Whakahekea te hautanga \frac{11856}{330} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 6.

$$\frac{1976}{55}$$

Tauwehe

$$\frac{13 \cdot 19 \cdot 2 ^ {3}}{5 \cdot 11} = 35\frac{51}{55} = 35.92727272727273$$
