Whakaoti i te 83/8-21/2

$$8 \frac { 3 } { 8 } - 2 \frac { 1 } { 2 }$$

Aromātai

$$\frac{47}{8}=5.875$$

Ngā Upane Otinga

Whakareatia te 8 ki te 8, ka 64.

$$\frac{64+3}{8}-\frac{2\times 2+1}{2}$$

Tāpirihia te 64 ki te 3, ka 67.

$$\frac{67}{8}-\frac{2\times 2+1}{2}$$

Whakareatia te 2 ki te 2, ka 4.

$$\frac{67}{8}-\frac{4+1}{2}$$

Tāpirihia te 4 ki te 1, ka 5.

$$\frac{67}{8}-\frac{5}{2}$$

Ko te maha noa iti rawa atu o 8 me 2 ko 8. Me tahuri \frac{67}{8} me \frac{5}{2} ki te hautau me te tautūnga 8.

$$\frac{67}{8}-\frac{20}{8}$$

Tā te mea he rite te tauraro o \frac{67}{8} me \frac{20}{8}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{67-20}{8}$$

Tangohia te 20 i te 67, ka 47.

$$\frac{47}{8}$$

Tauwehe

$$\frac{47}{2 ^ {3}} = 5\frac{7}{8} = 5.875$$
