Ngā Upane Otinga

Whakahekea te hautanga \frac{4}{512} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$\frac{1}{2}\left(\frac{1}{128}+\frac{23}{256}\right)$$

Ko te maha noa iti rawa atu o 128 me 256 ko 256. Me tahuri \frac{1}{128} me \frac{23}{256} ki te hautau me te tautūnga 256.

$$\frac{1}{2}\left(\frac{2}{256}+\frac{23}{256}\right)$$

Tā te mea he rite te tauraro o \frac{2}{256} me \frac{23}{256}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{1}{2}\times \frac{2+23}{256}$$

Tāpirihia te 2 ki te 23, ka 25.

$$\frac{1}{2}\times \frac{25}{256}$$

Me whakarea te \frac{1}{2} ki te \frac{25}{256} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{1\times 25}{2\times 256}$$

Mahia ngā whakarea i roto i te hautanga \frac{1\times 25}{2\times 256}.

$$\frac{25}{512}$$

Tauwehe

$$\frac{5 ^ {2}}{2 ^ {9}} = 0.048828125$$
