Ngā Upane mō te Whakaoti Whārite Rārangi

Whakarohaina te \frac{58.25}{160} mā te whakarea i te taurunga me te tauraro ki te 100.

$$A_{2}=\frac{5825}{16000}\times 121+\frac{42.75}{100}+123$$

Whakahekea te hautanga \frac{5825}{16000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 25.

$$A_{2}=\frac{233}{640}\times 121+\frac{42.75}{100}+123$$

Tuhia te \frac{233}{640}\times 121 hei hautanga kotahi.

$$A_{2}=\frac{233\times 121}{640}+\frac{42.75}{100}+123$$

Whakareatia te 233 ki te 121, ka 28193.

$$A_{2}=\frac{28193}{640}+\frac{42.75}{100}+123$$

Whakarohaina te \frac{42.75}{100} mā te whakarea i te taurunga me te tauraro ki te 100.

$$A_{2}=\frac{28193}{640}+\frac{4275}{10000}+123$$

Whakahekea te hautanga \frac{4275}{10000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 25.

$$A_{2}=\frac{28193}{640}+\frac{171}{400}+123$$

Ko te maha noa iti rawa atu o 640 me 400 ko 3200. Me tahuri \frac{28193}{640} me \frac{171}{400} ki te hautau me te tautūnga 3200.

$$A_{2}=\frac{140965}{3200}+\frac{1368}{3200}+123$$

Tā te mea he rite te tauraro o \frac{140965}{3200} me \frac{1368}{3200}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$A_{2}=\frac{140965+1368}{3200}+123$$

Tāpirihia te 140965 ki te 1368, ka 142333.

$$A_{2}=\frac{142333}{3200}+123$$

Me tahuri te 123 ki te hautau \frac{393600}{3200}.

$$A_{2}=\frac{142333}{3200}+\frac{393600}{3200}$$

Tā te mea he rite te tauraro o \frac{142333}{3200} me \frac{393600}{3200}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$A_{2}=\frac{142333+393600}{3200}$$

Tāpirihia te 142333 ki te 393600, ka 535933.

$$A_{2}=\frac{535933}{3200}$$

Tautapa A_2

$$A_{2}≔167.4790625$$
