$$\frac{1307}{21}\approx 62.238095238$$

Ngā Upane Otinga

Tātaitia te pūtakerua o 169 kia tae ki 13.

$$63+\frac{13\times \frac{4}{7}}{6}-2$$

Tuhia te 13\times \frac{4}{7} hei hautanga kotahi.

$$63+\frac{\frac{13\times 4}{7}}{6}-2$$

Whakareatia te 13 ki te 4, ka 52.

$$63+\frac{\frac{52}{7}}{6}-2$$

Tuhia te \frac{\frac{52}{7}}{6} hei hautanga kotahi.

$$63+\frac{52}{7\times 6}-2$$

Whakareatia te 7 ki te 6, ka 42.

$$63+\frac{52}{42}-2$$

Whakahekea te hautanga \frac{52}{42} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$63+\frac{26}{21}-2$$

Me tahuri te 63 ki te hautau \frac{1323}{21}.

$$\frac{1323}{21}+\frac{26}{21}-2$$

Tā te mea he rite te tauraro o \frac{1323}{21} me \frac{26}{21}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{1323+26}{21}-2$$

Tāpirihia te 1323 ki te 26, ka 1349.

$$\frac{1349}{21}-2$$

Me tahuri te 2 ki te hautau \frac{42}{21}.

$$\frac{1349}{21}-\frac{42}{21}$$

Tā te mea he rite te tauraro o \frac{1349}{21} me \frac{42}{21}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{1349-42}{21}$$

Tangohia te 42 i te 1349, ka 1307.

$$\frac{1307}{21}$$

Tauwehe

$$\frac{1307}{3 \cdot 7} = 62\frac{5}{21} = 62.23809523809524$$
