Ngā Upane Otinga

Whakareatia te 4 ki te 10, ka 40. Whakareatia te 2 ki te 1, ka 2.

$$40+2+5\times \frac{1}{10}+1\times \frac{1}{100}+4\times \frac{1}{1000}$$

Tāpirihia te 40 ki te 2, ka 42.

$$42+5\times \frac{1}{10}+1\times \frac{1}{100}+4\times \frac{1}{1000}$$

Whakareatia te 5 ki te \frac{1}{10}, ka \frac{5}{10}.

$$42+\frac{5}{10}+1\times \frac{1}{100}+4\times \frac{1}{1000}$$

Whakahekea te hautanga \frac{5}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$42+\frac{1}{2}+1\times \frac{1}{100}+4\times \frac{1}{1000}$$

Me tahuri te 42 ki te hautau \frac{84}{2}.

$$\frac{84}{2}+\frac{1}{2}+1\times \frac{1}{100}+4\times \frac{1}{1000}$$

Tā te mea he rite te tauraro o \frac{84}{2} me \frac{1}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{84+1}{2}+1\times \frac{1}{100}+4\times \frac{1}{1000}$$

Tāpirihia te 84 ki te 1, ka 85.

$$\frac{85}{2}+1\times \frac{1}{100}+4\times \frac{1}{1000}$$

Whakareatia te 1 ki te \frac{1}{100}, ka \frac{1}{100}.

$$\frac{85}{2}+\frac{1}{100}+4\times \frac{1}{1000}$$

Ko te maha noa iti rawa atu o 2 me 100 ko 100. Me tahuri \frac{85}{2} me \frac{1}{100} ki te hautau me te tautūnga 100.

$$\frac{4250}{100}+\frac{1}{100}+4\times \frac{1}{1000}$$

Tā te mea he rite te tauraro o \frac{4250}{100} me \frac{1}{100}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{4250+1}{100}+4\times \frac{1}{1000}$$

Tāpirihia te 4250 ki te 1, ka 4251.

$$\frac{4251}{100}+4\times \frac{1}{1000}$$

Whakareatia te 4 ki te \frac{1}{1000}, ka \frac{4}{1000}.

$$\frac{4251}{100}+\frac{4}{1000}$$

Whakahekea te hautanga \frac{4}{1000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$\frac{4251}{100}+\frac{1}{250}$$

Ko te maha noa iti rawa atu o 100 me 250 ko 500. Me tahuri \frac{4251}{100} me \frac{1}{250} ki te hautau me te tautūnga 500.

$$\frac{21255}{500}+\frac{2}{500}$$

Tā te mea he rite te tauraro o \frac{21255}{500} me \frac{2}{500}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{21255+2}{500}$$

Tāpirihia te 21255 ki te 2, ka 21257.

$$\frac{21257}{500}$$

Tauwehe

$$\frac{29 \cdot 733}{2 ^ {2} \cdot 5 ^ {3}} = 42\frac{257}{500} = 42.514$$
