$$\frac{3\times 3}{3\left(r-2\right)}-\frac{2\left(r-2\right)}{3\left(r-2\right)}$$

Tā te mea he rite te tauraro o \frac{3\times 3}{3\left(r-2\right)} me \frac{2\left(r-2\right)}{3\left(r-2\right)}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{3\times 3-2\left(r-2\right)}{3\left(r-2\right)}$$
