Whakaoti i te 31/2+16/1

$$3 \frac { 1 } { 2 } + \frac { 16 } { 1 }$$

Aromātai

$$\frac{39}{2}=19.5$$

Ngā Upane Otinga

Whakareatia te 3 ki te 2, ka 6.

$$\frac{6+1}{2}+\frac{16}{1}$$

Tāpirihia te 6 ki te 1, ka 7.

$$\frac{7}{2}+\frac{16}{1}$$

Ka whakawehea he tau ki te tahi, hua ai ko ia anō.

$$\frac{7}{2}+16$$

Me tahuri te 16 ki te hautau \frac{32}{2}.

$$\frac{7}{2}+\frac{32}{2}$$

Tā te mea he rite te tauraro o \frac{7}{2} me \frac{32}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{7+32}{2}$$

Tāpirihia te 7 ki te 32, ka 39.

$$\frac{39}{2}$$

Tauwehe

$$\frac{3 \cdot 13}{2} = 19\frac{1}{2} = 19.5$$
