Whakaoti i te 10/5-1-4/6+8

$$\frac { 10 } { 5 - 1 } - \frac { 4 } { 6 + 8 }$$

Aromātai

$$\frac{31}{14}\approx 2.214285714$$

Ngā Upane Otinga

Tangohia te 1 i te 5, ka 4.

$$\frac{10}{4}-\frac{4}{6+8}$$

Whakahekea te hautanga \frac{10}{4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{5}{2}-\frac{4}{6+8}$$

Tāpirihia te 6 ki te 8, ka 14.

$$\frac{5}{2}-\frac{4}{14}$$

Whakahekea te hautanga \frac{4}{14} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{5}{2}-\frac{2}{7}$$

Ko te maha noa iti rawa atu o 2 me 7 ko 14. Me tahuri \frac{5}{2} me \frac{2}{7} ki te hautau me te tautūnga 14.

$$\frac{35}{14}-\frac{4}{14}$$

Tā te mea he rite te tauraro o \frac{35}{14} me \frac{4}{14}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{35-4}{14}$$

Tangohia te 4 i te 35, ka 31.

$$\frac{31}{14}$$

Tauwehe

$$\frac{31}{2 \cdot 7} = 2\frac{3}{14} = 2.2142857142857144$$
