Whakaoti i te 81/3-42/4=

$$8 \frac { 1 } { 3 } - 4 \frac { 2 } { 4 } =$$

Aromātai

$$\frac{23}{6}\approx 3.833333333$$

Ngā Upane Otinga

Whakareatia te 8 ki te 3, ka 24.

$$\frac{24+1}{3}-\frac{4\times 4+2}{4}$$

Tāpirihia te 24 ki te 1, ka 25.

$$\frac{25}{3}-\frac{4\times 4+2}{4}$$

Whakareatia te 4 ki te 4, ka 16.

$$\frac{25}{3}-\frac{16+2}{4}$$

Tāpirihia te 16 ki te 2, ka 18.

$$\frac{25}{3}-\frac{18}{4}$$

Whakahekea te hautanga \frac{18}{4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{25}{3}-\frac{9}{2}$$

Ko te maha noa iti rawa atu o 3 me 2 ko 6. Me tahuri \frac{25}{3} me \frac{9}{2} ki te hautau me te tautūnga 6.

$$\frac{50}{6}-\frac{27}{6}$$

Tā te mea he rite te tauraro o \frac{50}{6} me \frac{27}{6}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{50-27}{6}$$

Tangohia te 27 i te 50, ka 23.

$$\frac{23}{6}$$

Tauwehe

$$\frac{23}{2 \cdot 3} = 3\frac{5}{6} = 3.8333333333333335$$
