Whakaoti i te 92/12-39/12

$$9 \frac { 2 } { 12 } - 3 \frac { 9 } { 12 }$$

Aromātai

$$\frac{65}{12}\approx 5.416666667$$

Ngā Upane Otinga

Whakareatia te 9 ki te 12, ka 108.

$$\frac{108+2}{12}-\frac{3\times 12+9}{12}$$

Tāpirihia te 108 ki te 2, ka 110.

$$\frac{110}{12}-\frac{3\times 12+9}{12}$$

Whakahekea te hautanga \frac{110}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{55}{6}-\frac{3\times 12+9}{12}$$

Whakareatia te 3 ki te 12, ka 36.

$$\frac{55}{6}-\frac{36+9}{12}$$

Tāpirihia te 36 ki te 9, ka 45.

$$\frac{55}{6}-\frac{45}{12}$$

Whakahekea te hautanga \frac{45}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$\frac{55}{6}-\frac{15}{4}$$

Ko te maha noa iti rawa atu o 6 me 4 ko 12. Me tahuri \frac{55}{6} me \frac{15}{4} ki te hautau me te tautūnga 12.

$$\frac{110}{12}-\frac{45}{12}$$

Tā te mea he rite te tauraro o \frac{110}{12} me \frac{45}{12}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{110-45}{12}$$

Tangohia te 45 i te 110, ka 65.

$$\frac{65}{12}$$

Tauwehe

$$\frac{5 \cdot 13}{2 ^ {2} \cdot 3} = 5\frac{5}{12} = 5.416666666666667$$
