Whakaoti i te 81/6-62/5=

$$8 \frac { 1 } { 6 } - 6 \frac { 2 } { 5 } =$$

Aromātai

$$\frac{53}{30}\approx 1.766666667$$

Ngā Upane Otinga

Whakareatia te 8 ki te 6, ka 48.

$$\frac{48+1}{6}-\frac{6\times 5+2}{5}$$

Tāpirihia te 48 ki te 1, ka 49.

$$\frac{49}{6}-\frac{6\times 5+2}{5}$$

Whakareatia te 6 ki te 5, ka 30.

$$\frac{49}{6}-\frac{30+2}{5}$$

Tāpirihia te 30 ki te 2, ka 32.

$$\frac{49}{6}-\frac{32}{5}$$

Ko te maha noa iti rawa atu o 6 me 5 ko 30. Me tahuri \frac{49}{6} me \frac{32}{5} ki te hautau me te tautūnga 30.

$$\frac{245}{30}-\frac{192}{30}$$

Tā te mea he rite te tauraro o \frac{245}{30} me \frac{192}{30}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{245-192}{30}$$

Tangohia te 192 i te 245, ka 53.

$$\frac{53}{30}$$

Tauwehe

$$\frac{53}{2 \cdot 3 \cdot 5} = 1\frac{23}{30} = 1.7666666666666666$$
