Ngā Upane Otinga

Whakarohaina te \frac{12.4}{850} mā te whakarea i te taurunga me te tauraro ki te 10.

$$\frac{124}{8500}\times 2^{2}\times 100$$

Whakahekea te hautanga \frac{124}{8500} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$\frac{31}{2125}\times 2^{2}\times 100$$

Tātaihia te 2 mā te pū o 2, kia riro ko 4.

$$\frac{31}{2125}\times 4\times 100$$

Tuhia te \frac{31}{2125}\times 4 hei hautanga kotahi.

$$\frac{31\times 4}{2125}\times 100$$

Whakareatia te 31 ki te 4, ka 124.

$$\frac{124}{2125}\times 100$$

Tuhia te \frac{124}{2125}\times 100 hei hautanga kotahi.

$$\frac{124\times 100}{2125}$$
