Ngā Upane Otinga

Whakareatia te 3 ki te -64, ka -192.

$$\frac{-192}{-\frac{7}{31}}-64\times \frac{3\times 7+3}{7}$$

Whakawehe -192 ki te -\frac{7}{31} mā te whakarea -192 ki te tau huripoki o -\frac{7}{31}.

$$-192\left(-\frac{31}{7}\right)-64\times \frac{3\times 7+3}{7}$$

Tuhia te -192\left(-\frac{31}{7}\right) hei hautanga kotahi.

$$\frac{-192\left(-31\right)}{7}-64\times \frac{3\times 7+3}{7}$$

Whakareatia te -192 ki te -31, ka 5952.

$$\frac{5952}{7}-64\times \frac{3\times 7+3}{7}$$

Whakareatia te 3 ki te 7, ka 21.

$$\frac{5952}{7}-64\times \frac{21+3}{7}$$

Tāpirihia te 21 ki te 3, ka 24.

$$\frac{5952}{7}-64\times \frac{24}{7}$$

Tuhia te -64\times \frac{24}{7} hei hautanga kotahi.

$$\frac{5952}{7}+\frac{-64\times 24}{7}$$

Whakareatia te -64 ki te 24, ka -1536.

$$\frac{5952}{7}+\frac{-1536}{7}$$

Ka taea te hautanga \frac{-1536}{7} te tuhi anō ko -\frac{1536}{7} mā te tango i te tohu tōraro.

$$\frac{5952}{7}-\frac{1536}{7}$$

Tā te mea he rite te tauraro o \frac{5952}{7} me \frac{1536}{7}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{5952-1536}{7}$$

Tangohia te 1536 i te 5952, ka 4416.

$$\frac{4416}{7}$$

Tauwehe

$$\frac{2 ^ {6} \cdot 3 \cdot 23}{7} = 630\frac{6}{7} = 630.8571428571429$$
