Ko te maha noa iti rawa atu o 8 me 2 ko 8. Me tahuri \frac{3}{8} me \frac{1}{2} ki te hautau me te tautūnga 8.

$$\frac{3}{8}+\frac{4}{8}-\frac{1}{16}$$

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

$$\frac{3+4}{8}-\frac{1}{16}$$

Tāpirihia te 3 ki te 4, ka 7.

$$\frac{7}{8}-\frac{1}{16}$$

Ko te maha noa iti rawa atu o 8 me 16 ko 16. Me tahuri \frac{7}{8} me \frac{1}{16} ki te hautau me te tautūnga 16.

$$\frac{14}{16}-\frac{1}{16}$$

Tā te mea he rite te tauraro o \frac{14}{16} me \frac{1}{16}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{14-1}{16}$$

Tangohia te 1 i te 14, ka 13.

$$\frac{13}{16}$$

Tauwehe

$$\frac{13}{2 ^ {4}} = 0.8125$$
