Ngā Upane Otinga

Me tahuri ki tau ā-ira 3.14 ki te hautau \frac{314}{100}. Whakahekea te hautanga \frac{314}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{1}{3}\times \frac{157}{50}\times 2\times 2\times 5$$

Me whakarea te \frac{1}{3} ki te \frac{157}{50} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{1\times 157}{3\times 50}\times 2\times 2\times 5$$

Mahia ngā whakarea i roto i te hautanga \frac{1\times 157}{3\times 50}.

$$\frac{157}{150}\times 2\times 2\times 5$$

Tuhia te \frac{157}{150}\times 2 hei hautanga kotahi.

$$\frac{157\times 2}{150}\times 2\times 5$$

Whakareatia te 157 ki te 2, ka 314.

$$\frac{314}{150}\times 2\times 5$$

Whakahekea te hautanga \frac{314}{150} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{157}{75}\times 2\times 5$$

Tuhia te \frac{157}{75}\times 2 hei hautanga kotahi.

$$\frac{157\times 2}{75}\times 5$$

Whakareatia te 157 ki te 2, ka 314.

$$\frac{314}{75}\times 5$$

Tuhia te \frac{314}{75}\times 5 hei hautanga kotahi.

$$\frac{314\times 5}{75}$$

Whakareatia te 314 ki te 5, ka 1570.

$$\frac{1570}{75}$$

Whakahekea te hautanga \frac{1570}{75} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$\frac{314}{15}$$

Tauwehe

$$\frac{2 \cdot 157}{3 \cdot 5} = 20\frac{14}{15} = 20.933333333333334$$
