Whakareatia te 0.75 ki te 10, ka 7.5.

$$1.2-\frac{7.5}{0.6}=0.2$$

Whakarohaina te \frac{7.5}{0.6} mā te whakarea i te taurunga me te tauraro ki te 10.

$$1.2-\frac{75}{6}=0.2$$

Whakahekea te hautanga \frac{75}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$1.2-\frac{25}{2}=0.2$$

Me tahuri ki tau ā-ira 1.2 ki te hautau \frac{12}{10}. Whakahekea te hautanga \frac{12}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{6}{5}-\frac{25}{2}=0.2$$

Ko te maha noa iti rawa atu o 5 me 2 ko 10. Me tahuri \frac{6}{5} me \frac{25}{2} ki te hautau me te tautūnga 10.

$$\frac{12}{10}-\frac{125}{10}=0.2$$

Tā te mea he rite te tauraro o \frac{12}{10} me \frac{125}{10}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{12-125}{10}=0.2$$

Tangohia te 125 i te 12, ka -113.

$$-\frac{113}{10}=0.2$$

Me tahuri ki tau ā-ira 0.2 ki te hautau \frac{2}{10}. Whakahekea te hautanga \frac{2}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$-\frac{113}{10}=\frac{1}{5}$$

Ko te maha noa iti rawa atu o 10 me 5 ko 10. Me tahuri -\frac{113}{10} me \frac{1}{5} ki te hautau me te tautūnga 10.

$$-\frac{113}{10}=\frac{2}{10}$$

Whakatauritea te -\frac{113}{10} me te \frac{2}{10}.
