Ngā Upane Otinga

Tangohia te 1.333 i te 1.3, ka -0.033.

$$-0.033+\frac{21}{15}$$

Whakahekea te hautanga \frac{21}{15} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$-0.033+\frac{7}{5}$$

Me tahuri ki tau ā-ira -0.033 ki te hautau -\frac{33}{1000}.

$$-\frac{33}{1000}+\frac{7}{5}$$

Ko te maha noa iti rawa atu o 1000 me 5 ko 1000. Me tahuri -\frac{33}{1000} me \frac{7}{5} ki te hautau me te tautūnga 1000.

$$-\frac{33}{1000}+\frac{1400}{1000}$$

Tā te mea he rite te tauraro o -\frac{33}{1000} me \frac{1400}{1000}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-33+1400}{1000}$$
