Whakahekea te hautanga \frac{6}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$10+3\times \frac{3}{50}\times 2-2$$

Tuhia te 3\times \frac{3}{50} hei hautanga kotahi.

$$10+\frac{3\times 3}{50}\times 2-2$$

Whakareatia te 3 ki te 3, ka 9.

$$10+\frac{9}{50}\times 2-2$$

Tuhia te \frac{9}{50}\times 2 hei hautanga kotahi.

$$10+\frac{9\times 2}{50}-2$$

Whakareatia te 9 ki te 2, ka 18.

$$10+\frac{18}{50}-2$$

Whakahekea te hautanga \frac{18}{50} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$10+\frac{9}{25}-2$$

Me tahuri te 10 ki te hautau \frac{250}{25}.

$$\frac{250}{25}+\frac{9}{25}-2$$

Tā te mea he rite te tauraro o \frac{250}{25} me \frac{9}{25}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{250+9}{25}-2$$

Tāpirihia te 250 ki te 9, ka 259.

$$\frac{259}{25}-2$$

Me tahuri te 2 ki te hautau \frac{50}{25}.

$$\frac{259}{25}-\frac{50}{25}$$

Tā te mea he rite te tauraro o \frac{259}{25} me \frac{50}{25}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{259-50}{25}$$

Tangohia te 50 i te 259, ka 209.

$$\frac{209}{25}$$

Tauwehe

$$\frac{11 \cdot 19}{5 ^ {2}} = 8\frac{9}{25} = 8.36$$
