Whakarohaina te \frac{243}{1.5} mā te whakarea i te taurunga me te tauraro ki te 10.

$$243+\frac{2430}{15}+\frac{243}{1.5}\times \frac{2}{3}$$

Whakawehea te 2430 ki te 15, kia riro ko 162.

$$243+162+\frac{243}{1.5}\times \frac{2}{3}$$

Tāpirihia te 243 ki te 162, ka 405.

$$405+\frac{243}{1.5}\times \frac{2}{3}$$

Whakarohaina te \frac{243}{1.5} mā te whakarea i te taurunga me te tauraro ki te 10.

$$405+\frac{2430}{15}\times \frac{2}{3}$$

Whakawehea te 2430 ki te 15, kia riro ko 162.

$$405+162\times \frac{2}{3}$$

Tuhia te 162\times \frac{2}{3} hei hautanga kotahi.

$$405+\frac{162\times 2}{3}$$

Whakareatia te 162 ki te 2, ka 324.

$$405+\frac{324}{3}$$

Whakawehea te 324 ki te 3, kia riro ko 108.

$$405+108$$

Tāpirihia te 405 ki te 108, ka 513.
