Ngā Upane Otinga

Tātaihia te 0.3 mā te pū o 2, kia riro ko 0.09.

$$\frac{0.09}{\frac{112}{260}}$$

Whakahekea te hautanga \frac{112}{260} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$\frac{0.09}{\frac{28}{65}}$$

Whakawehe 0.09 ki te \frac{28}{65} mā te whakarea 0.09 ki te tau huripoki o \frac{28}{65}.

$$0.09\times \frac{65}{28}$$

Me tahuri ki tau ā-ira 0.09 ki te hautau \frac{9}{100}.

$$\frac{9}{100}\times \frac{65}{28}$$

Me whakarea te \frac{9}{100} ki te \frac{65}{28} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{9\times 65}{100\times 28}$$

Mahia ngā whakarea i roto i te hautanga \frac{9\times 65}{100\times 28}.

$$\frac{585}{2800}$$

Whakahekea te hautanga \frac{585}{2800} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$\frac{117}{560}$$

Tauwehe

$$\frac{13 \cdot 3 ^ {2}}{5 \cdot 7 \cdot 2 ^ {4}} = 0.20892857142857144$$
