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.

$$\frac{1}{3}\times \frac{157}{50}\times 7^{2}\times 17.2$$

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

$$\frac{1\times 157}{3\times 50}\times 7^{2}\times 17.2$$

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

$$\frac{157}{150}\times 7^{2}\times 17.2$$

Tātaihia te 7 mā te pū o 2, kia riro ko 49.

$$\frac{157}{150}\times 49\times 17.2$$

Tuhia te \frac{157}{150}\times 49 hei hautanga kotahi.

$$\frac{157\times 49}{150}\times 17.2$$

Whakareatia te 157 ki te 49, ka 7693.

$$\frac{7693}{150}\times 17.2$$

Me tahuri ki tau ā-ira 17.2 ki te hautau \frac{172}{10}. Whakahekea te hautanga \frac{172}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{7693}{150}\times \frac{86}{5}$$

Me whakarea te \frac{7693}{150} ki te \frac{86}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{7693\times 86}{150\times 5}$$

Mahia ngā whakarea i roto i te hautanga \frac{7693\times 86}{150\times 5}.

$$\frac{661598}{750}$$

Whakahekea te hautanga \frac{661598}{750} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{330799}{375}$$

Tauwehe

$$\frac{43 \cdot 157 \cdot 7 ^ {2}}{3 \cdot 5 ^ {3}} = 882\frac{49}{375} = 882.1306666666667$$
