Tāpirihia te 92 ki te 1, ka 93.

$$\frac{98}{5}+\frac{93}{4}+\frac{16\times 2+1}{2}$$

Ko te maha noa iti rawa atu o 5 me 4 ko 20. Me tahuri \frac{98}{5} me \frac{93}{4} ki te hautau me te tautūnga 20.

$$\frac{392}{20}+\frac{465}{20}+\frac{16\times 2+1}{2}$$

Tā te mea he rite te tauraro o \frac{392}{20} me \frac{465}{20}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{392+465}{20}+\frac{16\times 2+1}{2}$$

Tāpirihia te 392 ki te 465, ka 857.

$$\frac{857}{20}+\frac{16\times 2+1}{2}$$

Whakareatia te 16 ki te 2, ka 32.
