Ngā Upane Otinga

Tuhia te 2\times \frac{22}{7} hei hautanga kotahi.

$$\frac{2\times 22}{7}\times 2.25\times 9.5$$

Whakareatia te 2 ki te 22, ka 44.

$$\frac{44}{7}\times 2.25\times 9.5$$

Me tahuri ki tau ā-ira 2.25 ki te hautau \frac{225}{100}. Whakahekea te hautanga \frac{225}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 25.

$$\frac{44}{7}\times \frac{9}{4}\times 9.5$$

Me whakarea te \frac{44}{7} ki te \frac{9}{4} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{44\times 9}{7\times 4}\times 9.5$$

Mahia ngā whakarea i roto i te hautanga \frac{44\times 9}{7\times 4}.

$$\frac{396}{28}\times 9.5$$

Whakahekea te hautanga \frac{396}{28} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$\frac{99}{7}\times 9.5$$

Me tahuri ki tau ā-ira 9.5 ki te hautau \frac{95}{10}. Whakahekea te hautanga \frac{95}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$\frac{99}{7}\times \frac{19}{2}$$

Me whakarea te \frac{99}{7} ki te \frac{19}{2} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{99\times 19}{7\times 2}$$

Mahia ngā whakarea i roto i te hautanga \frac{99\times 19}{7\times 2}.

$$\frac{1881}{14}$$

Tauwehe

$$\frac{11 \cdot 19 \cdot 3 ^ {2}}{2 \cdot 7} = 134\frac{5}{14} = 134.35714285714286$$
