Aromātai

$$\frac{569}{56}\approx 10.160714286$$

Ngā Upane Otinga

Ko te maha noa iti rawa atu o 7 me 8 ko 56. Me tahuri \frac{2}{7} me \frac{7}{8} ki te hautau me te tautūnga 56.

$$\frac{16}{56}+\frac{49}{56}+9$$

Tā te mea he rite te tauraro o \frac{16}{56} me \frac{49}{56}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{16+49}{56}+9$$

Tāpirihia te 16 ki te 49, ka 65.

$$\frac{65}{56}+9$$

Me tahuri te 9 ki te hautau \frac{504}{56}.

$$\frac{65}{56}+\frac{504}{56}$$

Tā te mea he rite te tauraro o \frac{65}{56} me \frac{504}{56}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{65+504}{56}$$

Tāpirihia te 65 ki te 504, ka 569.

$$\frac{569}{56}$$

Tauwehe

$$\frac{569}{2 ^ {3} \cdot 7} = 10\frac{9}{56} = 10.160714285714286$$
