Ngā Upane Otinga

Whakawehe \frac{8}{13} ki te \frac{5}{2} mā te whakarea \frac{8}{13} ki te tau huripoki o \frac{5}{2}.

$$\frac{8}{13}\times \frac{2}{5}-\frac{4}{5}\times \frac{8}{13}$$

Me whakarea te \frac{8}{13} ki te \frac{2}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{8\times 2}{13\times 5}-\frac{4}{5}\times \frac{8}{13}$$

Mahia ngā whakarea i roto i te hautanga \frac{8\times 2}{13\times 5}.

$$\frac{16}{65}-\frac{4}{5}\times \frac{8}{13}$$

Me whakarea te \frac{4}{5} ki te \frac{8}{13} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{16}{65}-\frac{4\times 8}{5\times 13}$$

Mahia ngā whakarea i roto i te hautanga \frac{4\times 8}{5\times 13}.

$$\frac{16}{65}-\frac{32}{65}$$

Tā te mea he rite te tauraro o \frac{16}{65} me \frac{32}{65}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{16-32}{65}$$

Tangohia te 32 i te 16, ka -16.

$$-\frac{16}{65}$$
