Me tahuri te 2 ki te hautau \frac{8}{4}.

$$\left(\frac{0.25}{\frac{8}{4}-\frac{3}{4}}+1.8\right)\times 3$$

Tā te mea he rite te tauraro o \frac{8}{4} me \frac{3}{4}, me tango rāua mā te tango i ō raua taurunga.

$$\left(\frac{0.25}{\frac{8-3}{4}}+1.8\right)\times 3$$

Tangohia te 3 i te 8, ka 5.

$$\left(\frac{0.25}{\frac{5}{4}}+1.8\right)\times 3$$

Whakawehe 0.25 ki te \frac{5}{4} mā te whakarea 0.25 ki te tau huripoki o \frac{5}{4}.

$$\left(0.25\times \frac{4}{5}+1.8\right)\times 3$$

Me tahuri ki tau ā-ira 0.25 ki te hautau \frac{25}{100}. Whakahekea te hautanga \frac{25}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 25.

$$\left(\frac{1}{4}\times \frac{4}{5}+1.8\right)\times 3$$

Me whakarea te \frac{1}{4} ki te \frac{4}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\left(\frac{1\times 4}{4\times 5}+1.8\right)\times 3$$

Me whakakore tahi te 4 i te taurunga me te tauraro.

$$\left(\frac{1}{5}+1.8\right)\times 3$$

Me tahuri ki tau ā-ira 1.8 ki te hautau \frac{18}{10}. Whakahekea te hautanga \frac{18}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\left(\frac{1}{5}+\frac{9}{5}\right)\times 3$$

Tā te mea he rite te tauraro o \frac{1}{5} me \frac{9}{5}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{1+9}{5}\times 3$$

Tāpirihia te 1 ki te 9, ka 10.

$$\frac{10}{5}\times 3$$

Whakawehea te 10 ki te 5, kia riro ko 2.

$$2\times 3$$

Whakareatia te 2 ki te 3, ka 6.

$$6$$

Tauwehe

$$2\times 3$$
