Ngā Upane Otinga

Me tahuri te 3 ki te hautau \frac{24}{8}.

$$\frac{4}{5}\times \frac{\frac{24}{8}-\frac{3}{8}}{\frac{7}{10}}$$

Tā te mea he rite te tauraro o \frac{24}{8} me \frac{3}{8}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{4}{5}\times \frac{\frac{24-3}{8}}{\frac{7}{10}}$$

Tangohia te 3 i te 24, ka 21.

$$\frac{4}{5}\times \frac{\frac{21}{8}}{\frac{7}{10}}$$

Whakawehe \frac{21}{8} ki te \frac{7}{10} mā te whakarea \frac{21}{8} ki te tau huripoki o \frac{7}{10}.

$$\frac{4}{5}\times \frac{21}{8}\times \frac{10}{7}$$

Me whakarea te \frac{21}{8} ki te \frac{10}{7} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{4}{5}\times \frac{21\times 10}{8\times 7}$$

Mahia ngā whakarea i roto i te hautanga \frac{21\times 10}{8\times 7}.

$$\frac{4}{5}\times \frac{210}{56}$$

Whakahekea te hautanga \frac{210}{56} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 14.

$$\frac{4}{5}\times \frac{15}{4}$$

Me whakarea te \frac{4}{5} ki te \frac{15}{4} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{4\times 15}{5\times 4}$$

Me whakakore tahi te 4 i te taurunga me te tauraro.

$$\frac{15}{5}$$

Whakawehea te 15 ki te 5, kia riro ko 3.
