Whakaoti i te -9*n/3n-3n/n*3n/n-3n

$$- 9 \cdot \frac { n } { 3 n } - \frac { 3 n } { n } \times \frac { 3 n } { n - 3 n }$$

Aromātai

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

Ngā Upane Otinga

Me whakakore tahi te n i te taurunga me te tauraro.

$$-9\times \frac{1}{3}-\frac{3n}{n}\times \frac{3n}{n-3n}$$

Whakareatia te -9 ki te \frac{1}{3}, ka \frac{-9}{3}.

$$\frac{-9}{3}-\frac{3n}{n}\times \frac{3n}{n-3n}$$

Whakawehea te -9 ki te 3, kia riro ko -3.

$$-3-\frac{3n}{n}\times \frac{3n}{n-3n}$$

Me whakakore tahi te n i te taurunga me te tauraro.

$$-3-3\times \frac{3n}{n-3n}$$

Pahekotia te n me -3n, ka -2n.

$$-3-3\times \frac{3n}{-2n}$$

Me whakakore tahi te n i te taurunga me te tauraro.

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

Ka taea te hautanga \frac{3}{-2} te tuhi anō ko -\frac{3}{2} mā te tango i te tohu tōraro.

$$-3-3\left(-\frac{3}{2}\right)$$

Tuhia te 3\left(-\frac{3}{2}\right) hei hautanga kotahi.

$$-3-\frac{3\left(-3\right)}{2}$$

Whakareatia te 3 ki te -3, ka -9.

$$-3-\frac{-9}{2}$$

Ka taea te hautanga \frac{-9}{2} te tuhi anō ko -\frac{9}{2} mā te tango i te tohu tōraro.

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

Ko te tauaro o -\frac{9}{2} ko \frac{9}{2}.

$$-3+\frac{9}{2}$$

Me tahuri te -3 ki te hautau -\frac{6}{2}.

$$-\frac{6}{2}+\frac{9}{2}$$

Tā te mea he rite te tauraro o -\frac{6}{2} me \frac{9}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-6+9}{2}$$

Tāpirihia te -6 ki te 9, ka 3.

$$\frac{3}{2}$$

Tauwehe

$$\frac{3}{2} = 1\frac{1}{2} = 1.5$$
