Ngā Upane Otinga

Whakawehe 4 ki te \frac{\frac{3}{7}-1}{4} mā te whakarea 4 ki te tau huripoki o \frac{\frac{3}{7}-1}{4}.

$$\frac{4\times 4}{\frac{3}{7}-1}\times 2$$

Whakareatia te 4 ki te 4, ka 16.

$$\frac{16}{\frac{3}{7}-1}\times 2$$

Me tahuri te 1 ki te hautau \frac{7}{7}.

$$\frac{16}{\frac{3}{7}-\frac{7}{7}}\times 2$$

Tā te mea he rite te tauraro o \frac{3}{7} me \frac{7}{7}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{16}{\frac{3-7}{7}}\times 2$$

Tangohia te 7 i te 3, ka -4.

$$\frac{16}{-\frac{4}{7}}\times 2$$

Whakawehe 16 ki te -\frac{4}{7} mā te whakarea 16 ki te tau huripoki o -\frac{4}{7}.

$$16\left(-\frac{7}{4}\right)\times 2$$

Tuhia te 16\left(-\frac{7}{4}\right) hei hautanga kotahi.

$$\frac{16\left(-7\right)}{4}\times 2$$

Whakareatia te 16 ki te -7, ka -112.

$$\frac{-112}{4}\times 2$$

Whakawehea te -112 ki te 4, kia riro ko -28.

$$-28\times 2$$

Whakareatia te -28 ki te 2, ka -56.
