Tuhia te 5\times \frac{2}{3} hei hautanga kotahi.

$$8-\frac{5\times 2}{3}-0.7=\frac{119}{30}$$

Whakareatia te 5 ki te 2, ka 10.

$$8-\frac{10}{3}-0.7=\frac{119}{30}$$

Me tahuri te 8 ki te hautau \frac{24}{3}.

$$\frac{24}{3}-\frac{10}{3}-0.7=\frac{119}{30}$$

Tā te mea he rite te tauraro o \frac{24}{3} me \frac{10}{3}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{24-10}{3}-0.7=\frac{119}{30}$$

Tangohia te 10 i te 24, ka 14.

$$\frac{14}{3}-0.7=\frac{119}{30}$$

Me tahuri ki tau ā-ira 0.7 ki te hautau \frac{7}{10}.

$$\frac{14}{3}-\frac{7}{10}=\frac{119}{30}$$

Ko te maha noa iti rawa atu o 3 me 10 ko 30. Me tahuri \frac{14}{3} me \frac{7}{10} ki te hautau me te tautūnga 30.

$$\frac{140}{30}-\frac{21}{30}=\frac{119}{30}$$

Tā te mea he rite te tauraro o \frac{140}{30} me \frac{21}{30}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{140-21}{30}=\frac{119}{30}$$

Tangohia te 21 i te 140, ka 119.

$$\frac{119}{30}=\frac{119}{30}$$

Whakatauritea te \frac{119}{30} me te \frac{119}{30}.
