Tā te mea he rite te tauraro o \frac{2078}{100} me \frac{251}{100}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{2078+251}{100}-\frac{1212}{100}-\frac{66}{10}$$

Tāpirihia te 2078 ki te 251, ka 2329.

$$\frac{2329}{100}-\frac{1212}{100}-\frac{66}{10}$$

Tā te mea he rite te tauraro o \frac{2329}{100} me \frac{1212}{100}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{2329-1212}{100}-\frac{66}{10}$$

Tangohia te 1212 i te 2329, ka 1117.

$$\frac{1117}{100}-\frac{66}{10}$$

Whakahekea te hautanga \frac{66}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{1117}{100}-\frac{33}{5}$$

Ko te maha noa iti rawa atu o 100 me 5 ko 100. Me tahuri \frac{1117}{100} me \frac{33}{5} ki te hautau me te tautūnga 100.

$$\frac{1117}{100}-\frac{660}{100}$$

Tā te mea he rite te tauraro o \frac{1117}{100} me \frac{660}{100}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{1117-660}{100}$$

Tangohia te 660 i te 1117, ka 457.

$$\frac{457}{100}$$

Tauwehe

$$\frac{457}{2 ^ {2} \cdot 5 ^ {2}} = 4\frac{57}{100} = 4.57$$
