Ngā Upane Otinga

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

$$\frac{2\times 22}{7}\times 2.25\left(9.5+2.25\right)$$

Whakareatia te 2 ki te 22, ka 44.

$$\frac{44}{7}\times 2.25\left(9.5+2.25\right)$$

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.

$$\frac{44}{7}\times \frac{9}{4}\left(9.5+2.25\right)$$

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

$$\frac{44\times 9}{7\times 4}\left(9.5+2.25\right)$$

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

$$\frac{396}{28}\left(9.5+2.25\right)$$

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

$$\frac{99}{7}\left(9.5+2.25\right)$$

Tāpirihia te 9.5 ki te 2.25, ka 11.75.

$$\frac{99}{7}\times 11.75$$

Me tahuri ki tau ā-ira 11.75 ki te hautau \frac{1175}{100}. Whakahekea te hautanga \frac{1175}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 25.

$$\frac{99}{7}\times \frac{47}{4}$$

Me whakarea te \frac{99}{7} ki te \frac{47}{4} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{99\times 47}{7\times 4}$$

Mahia ngā whakarea i roto i te hautanga \frac{99\times 47}{7\times 4}.

$$\frac{4653}{28}$$

Tauwehe

$$\frac{11 \cdot 47 \cdot 3 ^ {2}}{7 \cdot 2 ^ {2}} = 166\frac{5}{28} = 166.17857142857142$$
