Ngā Upane Otinga

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

$$\frac{2\times 22}{7}\times \frac{35}{2}\times \frac{35}{2}$$

Whakareatia te 2 ki te 22, ka 44.

$$\frac{44}{7}\times \frac{35}{2}\times \frac{35}{2}$$

Me whakarea te \frac{44}{7} ki te \frac{35}{2} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{44\times 35}{7\times 2}\times \frac{35}{2}$$

Mahia ngā whakarea i roto i te hautanga \frac{44\times 35}{7\times 2}.

$$\frac{1540}{14}\times \frac{35}{2}$$

Whakawehea te 1540 ki te 14, kia riro ko 110.

$$110\times \frac{35}{2}$$

Tuhia te 110\times \frac{35}{2} hei hautanga kotahi.

$$\frac{110\times 35}{2}$$

Whakareatia te 110 ki te 35, ka 3850.

$$\frac{3850}{2}$$

Whakawehea te 3850 ki te 2, kia riro ko 1925.

$$1925$$
