Ngā Upane Otinga

Whakahekea te hautanga \frac{254}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{151}{5}+\frac{127}{3}-127$$

Ko te maha noa iti rawa atu o 5 me 3 ko 15. Me tahuri \frac{151}{5} me \frac{127}{3} ki te hautau me te tautūnga 15.

$$\frac{453}{15}+\frac{635}{15}-127$$

Tā te mea he rite te tauraro o \frac{453}{15} me \frac{635}{15}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{453+635}{15}-127$$

Tāpirihia te 453 ki te 635, ka 1088.

$$\frac{1088}{15}-127$$

Me tahuri te 127 ki te hautau \frac{1905}{15}.

$$\frac{1088}{15}-\frac{1905}{15}$$

Tā te mea he rite te tauraro o \frac{1088}{15} me \frac{1905}{15}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{1088-1905}{15}$$

Tangohia te 1905 i te 1088, ka -817.

$$-\frac{817}{15}$$

Tauwehe

$$-\frac{817}{15} = -54\frac{7}{15} = -54.46666666666667$$
