Whakareatia te 19 ki te 8, ka 152.

$$\frac{152+1}{8}-\frac{5\times 4+3}{4}-\frac{9\times 8+1}{8}-1.25$$

Tāpirihia te 152 ki te 1, ka 153.

$$\frac{153}{8}-\frac{5\times 4+3}{4}-\frac{9\times 8+1}{8}-1.25$$

Whakareatia te 5 ki te 4, ka 20.

$$\frac{153}{8}-\frac{20+3}{4}-\frac{9\times 8+1}{8}-1.25$$

Tāpirihia te 20 ki te 3, ka 23.

$$\frac{153}{8}-\frac{23}{4}-\frac{9\times 8+1}{8}-1.25$$

Ko te maha noa iti rawa atu o 8 me 4 ko 8. Me tahuri \frac{153}{8} me \frac{23}{4} ki te hautau me te tautūnga 8.

$$\frac{153}{8}-\frac{46}{8}-\frac{9\times 8+1}{8}-1.25$$

Tā te mea he rite te tauraro o \frac{153}{8} me \frac{46}{8}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{153-46}{8}-\frac{9\times 8+1}{8}-1.25$$

Tangohia te 46 i te 153, ka 107.

$$\frac{107}{8}-\frac{9\times 8+1}{8}-1.25$$

Whakareatia te 9 ki te 8, ka 72.

$$\frac{107}{8}-\frac{72+1}{8}-1.25$$

Tāpirihia te 72 ki te 1, ka 73.

$$\frac{107}{8}-\frac{73}{8}-1.25$$

Tā te mea he rite te tauraro o \frac{107}{8} me \frac{73}{8}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{107-73}{8}-1.25$$

Tangohia te 73 i te 107, ka 34.

$$\frac{34}{8}-1.25$$

Whakahekea te hautanga \frac{34}{8} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{17}{4}-1.25$$

Me tahuri ki tau ā-ira 1.25 ki te hautau \frac{125}{100}. Whakahekea te hautanga \frac{125}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 25.

$$\frac{17}{4}-\frac{5}{4}$$

Tā te mea he rite te tauraro o \frac{17}{4} me \frac{5}{4}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{17-5}{4}$$

Tangohia te 5 i te 17, ka 12.

$$\frac{12}{4}$$

Whakawehea te 12 ki te 4, kia riro ko 3.
