Whakaoti i te 2/5div2+7/30

$$\frac { 2 } { 5 } \div 2 + \frac { 7 } { 30 }$$

Aromātai

$$\frac{13}{30}\approx 0.433333333$$

Ngā Upane Otinga

Tuhia te \frac{\frac{2}{5}}{2} hei hautanga kotahi.

$$\frac{2}{5\times 2}+\frac{7}{30}$$

Me whakakore tahi te 2 i te taurunga me te tauraro.

$$\frac{1}{5}+\frac{7}{30}$$

Ko te maha noa iti rawa atu o 5 me 30 ko 30. Me tahuri \frac{1}{5} me \frac{7}{30} ki te hautau me te tautūnga 30.

$$\frac{6}{30}+\frac{7}{30}$$

Tā te mea he rite te tauraro o \frac{6}{30} me \frac{7}{30}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{6+7}{30}$$

Tāpirihia te 6 ki te 7, ka 13.

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

Tauwehe

$$\frac{13}{2 \cdot 3 \cdot 5} = 0.43333333333333335$$
