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

Aromātai

$$\frac{29}{28}\approx 1.035714286$$

Ngā Upane Otinga

Ko te maha noa iti rawa atu o 4 me 7 ko 28. Me tahuri \frac{1}{4} me \frac{2}{7} ki te hautau me te tautūnga 28.

$$\frac{7}{28}+\frac{8}{28}+\frac{1}{2}$$

Tā te mea he rite te tauraro o \frac{7}{28} me \frac{8}{28}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{7+8}{28}+\frac{1}{2}$$

Tāpirihia te 7 ki te 8, ka 15.

$$\frac{15}{28}+\frac{1}{2}$$

Ko te maha noa iti rawa atu o 28 me 2 ko 28. Me tahuri \frac{15}{28} me \frac{1}{2} ki te hautau me te tautūnga 28.

$$\frac{15}{28}+\frac{14}{28}$$

Tā te mea he rite te tauraro o \frac{15}{28} me \frac{14}{28}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{15+14}{28}$$

Tāpirihia te 15 ki te 14, ka 29.

$$\frac{29}{28}$$

Tauwehe

$$\frac{29}{2 ^ {2} \cdot 7} = 1\frac{1}{28} = 1.0357142857142858$$
