$$1.1115$$

Ngā Upane Otinga

Whakarohaina te \frac{-0.0405}{-0.3} mā te whakarea i te taurunga me te tauraro ki te 10000.

$$0.72-\frac{-405}{-3000}\left(-2.9\right)$$

Whakahekea te hautanga \frac{-405}{-3000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -15.

$$0.72-\frac{27}{200}\left(-2.9\right)$$

Me tahuri ki tau ā-ira -2.9 ki te hautau -\frac{29}{10}.

$$0.72-\frac{27}{200}\left(-\frac{29}{10}\right)$$

Me whakarea te \frac{27}{200} ki te -\frac{29}{10} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$0.72-\frac{27\left(-29\right)}{200\times 10}$$

Mahia ngā whakarea i roto i te hautanga \frac{27\left(-29\right)}{200\times 10}.

$$0.72-\frac{-783}{2000}$$

Ka taea te hautanga \frac{-783}{2000} te tuhi anō ko -\frac{783}{2000} mā te tango i te tohu tōraro.

$$0.72-\left(-\frac{783}{2000}\right)$$

Ko te tauaro o -\frac{783}{2000} ko \frac{783}{2000}.

$$0.72+\frac{783}{2000}$$

Me tahuri ki tau ā-ira 0.72 ki te hautau \frac{72}{100}. Whakahekea te hautanga \frac{72}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$\frac{18}{25}+\frac{783}{2000}$$

Ko te maha noa iti rawa atu o 25 me 2000 ko 2000. Me tahuri \frac{18}{25} me \frac{783}{2000} ki te hautau me te tautūnga 2000.

$$\frac{1440}{2000}+\frac{783}{2000}$$

Tā te mea he rite te tauraro o \frac{1440}{2000} me \frac{783}{2000}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{1440+783}{2000}$$

Tāpirihia te 1440 ki te 783, ka 2223.

$$\frac{2223}{2000}$$

Tauwehe

$$\frac{13 \cdot 19 \cdot 3 ^ {2}}{2 ^ {4} \cdot 5 ^ {3}} = 1\frac{223}{2000} = 1.1115$$
