Ngā Upane Otinga

Whakawehe \frac{1}{2} ki te \frac{5}{8} mā te whakarea \frac{1}{2} ki te tau huripoki o \frac{5}{8}.

$$\frac{1}{2}\times \frac{8}{5}+\frac{1}{4}\times \frac{3}{5}\times \frac{3}{4}$$

Me whakarea te \frac{1}{2} ki te \frac{8}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{1\times 8}{2\times 5}+\frac{1}{4}\times \frac{3}{5}\times \frac{3}{4}$$

Mahia ngā whakarea i roto i te hautanga \frac{1\times 8}{2\times 5}.

$$\frac{8}{10}+\frac{1}{4}\times \frac{3}{5}\times \frac{3}{4}$$

Whakahekea te hautanga \frac{8}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{4}{5}+\frac{1}{4}\times \frac{3}{5}\times \frac{3}{4}$$

Me whakarea te \frac{1}{4} ki te \frac{3}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{4}{5}+\frac{1\times 3}{4\times 5}\times \frac{3}{4}$$

Mahia ngā whakarea i roto i te hautanga \frac{1\times 3}{4\times 5}.

$$\frac{4}{5}+\frac{3}{20}\times \frac{3}{4}$$

Me whakarea te \frac{3}{20} ki te \frac{3}{4} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{4}{5}+\frac{3\times 3}{20\times 4}$$

Mahia ngā whakarea i roto i te hautanga \frac{3\times 3}{20\times 4}.

$$\frac{4}{5}+\frac{9}{80}$$

Ko te maha noa iti rawa atu o 5 me 80 ko 80. Me tahuri \frac{4}{5} me \frac{9}{80} ki te hautau me te tautūnga 80.

$$\frac{64}{80}+\frac{9}{80}$$

Tā te mea he rite te tauraro o \frac{64}{80} me \frac{9}{80}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{64+9}{80}$$

Tāpirihia te 64 ki te 9, ka 73.

$$\frac{73}{80}$$

Tauwehe

$$\frac{73}{2 ^ {4} \cdot 5} = 0.9125$$
