Whakaoti i te 21/2-7/6=

$$2 \frac { 1 } { 2 } - \frac { 7 } { 6 } =$$

Aromātai

$$\frac{4}{3}\approx 1.333333333$$

Ngā Upane Otinga

Whakareatia te 2 ki te 2, ka 4.

$$\frac{4+1}{2}-\frac{7}{6}$$

Tāpirihia te 4 ki te 1, ka 5.

$$\frac{5}{2}-\frac{7}{6}$$

Ko te maha noa iti rawa atu o 2 me 6 ko 6. Me tahuri \frac{5}{2} me \frac{7}{6} ki te hautau me te tautūnga 6.

$$\frac{15}{6}-\frac{7}{6}$$

Tā te mea he rite te tauraro o \frac{15}{6} me \frac{7}{6}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{15-7}{6}$$

Tangohia te 7 i te 15, ka 8.

$$\frac{8}{6}$$

Whakahekea te hautanga \frac{8}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{4}{3}$$

Tauwehe

$$\frac{2 ^ {2}}{3} = 1\frac{1}{3} = 1.3333333333333333$$
