Whakaoti i te {frac{2/3}+1/5}{30}

$$\frac { { \frac { 2 } { 3 } } + \frac { 1 } { 5 } } { 30 }$$

Aromātai

$$\frac{13}{450}\approx 0.028888889$$

Ngā Upane Otinga

Ko te maha noa iti rawa atu o 3 me 5 ko 15. Me tahuri \frac{2}{3} me \frac{1}{5} ki te hautau me te tautūnga 15.

$$\frac{\frac{10}{15}+\frac{3}{15}}{30}$$

Tā te mea he rite te tauraro o \frac{10}{15} me \frac{3}{15}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{\frac{10+3}{15}}{30}$$

Tāpirihia te 10 ki te 3, ka 13.

$$\frac{\frac{13}{15}}{30}$$

Tuhia te \frac{\frac{13}{15}}{30} hei hautanga kotahi.

$$\frac{13}{15\times 30}$$

Whakareatia te 15 ki te 30, ka 450.

$$\frac{13}{450}$$

Tauwehe

$$\frac{13}{2 \cdot 3 ^ {2} \cdot 5 ^ {2}} = 0.028888888888888888$$
