Ngā Upane Otinga

Me tahuri te 4 ki te hautau \frac{20}{5}.

$$\frac{5.2}{\frac{20}{5}-\frac{4}{5}}$$

Tā te mea he rite te tauraro o \frac{20}{5} me \frac{4}{5}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{5.2}{\frac{20-4}{5}}$$

Tangohia te 4 i te 20, ka 16.

$$\frac{5.2}{\frac{16}{5}}$$

Whakawehe 5.2 ki te \frac{16}{5} mā te whakarea 5.2 ki te tau huripoki o \frac{16}{5}.

$$5.2\times \frac{5}{16}$$

Me tahuri ki tau ā-ira 5.2 ki te hautau \frac{52}{10}. Whakahekea te hautanga \frac{52}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{26}{5}\times \frac{5}{16}$$

Me whakarea te \frac{26}{5} ki te \frac{5}{16} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{26\times 5}{5\times 16}$$

Me whakakore tahi te 5 i te taurunga me te tauraro.

$$\frac{26}{16}$$

Whakahekea te hautanga \frac{26}{16} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{13}{8}$$

Tauwehe

$$\frac{13}{2 ^ {3}} = 1\frac{5}{8} = 1.625$$
