$$\left. \begin{array} { r } { 1 \frac { 3 } { 4 } } \\ { + 3 \frac { 1 } { 8 } } \end{array} \right.$$

Aromātai

$$\frac{39}{8}=4.875$$

Ngā Upane Otinga

Whakareatia te 1 ki te 4, ka 4.

$$\frac{4+3}{4}+\frac{3\times 8+1}{8}$$

Tāpirihia te 4 ki te 3, ka 7.

$$\frac{7}{4}+\frac{3\times 8+1}{8}$$

Whakareatia te 3 ki te 8, ka 24.

$$\frac{7}{4}+\frac{24+1}{8}$$

Tāpirihia te 24 ki te 1, ka 25.

$$\frac{7}{4}+\frac{25}{8}$$

Ko te maha noa iti rawa atu o 4 me 8 ko 8. Me tahuri \frac{7}{4} me \frac{25}{8} ki te hautau me te tautūnga 8.

$$\frac{14}{8}+\frac{25}{8}$$

Tā te mea he rite te tauraro o \frac{14}{8} me \frac{25}{8}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{14+25}{8}$$

Tāpirihia te 14 ki te 25, ka 39.

$$\frac{39}{8}$$

Tauwehe

$$\frac{3 \cdot 13}{2 ^ {3}} = 4\frac{7}{8} = 4.875$$
