Ngā Upane Otinga

Whakarohaina te \frac{4.5}{0.25} mā te whakarea i te taurunga me te tauraro ki te 100.

$$20\left(\frac{450}{25}+\frac{6}{0.2}\right)$$

Whakawehea te 450 ki te 25, kia riro ko 18.

$$20\left(18+\frac{6}{0.2}\right)$$

Whakarohaina te \frac{6}{0.2} mā te whakarea i te taurunga me te tauraro ki te 10.

$$20\left(18+\frac{60}{2}\right)$$

Whakawehea te 60 ki te 2, kia riro ko 30.

$$20\left(18+30\right)$$

Tāpirihia te 18 ki te 30, ka 48.

$$20\times 48$$

Whakareatia te 20 ki te 48, ka 960.

$$960$$

Tauwehe
