Whakaoti i te ((2/5)(2/3))+(1/2div2)

$$(( \frac{ 2 }{ 5 } )( \frac{ 2 }{ 3 } ))+( \frac{ 1 }{ 2 } \div 2)$$

$$\frac{31}{60}\approx 0.516666667$$

Ngā Upane Otinga

Me whakarea te \frac{2}{5} ki te \frac{2}{3} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

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

Mahia ngā whakarea i roto i te hautanga \frac{2\times 2}{5\times 3}.

$$\frac{4}{15}+\frac{\frac{1}{2}}{2}$$

Tuhia te \frac{\frac{1}{2}}{2} hei hautanga kotahi.

$$\frac{4}{15}+\frac{1}{2\times 2}$$

Whakareatia te 2 ki te 2, ka 4.

$$\frac{4}{15}+\frac{1}{4}$$

Ko te maha noa iti rawa atu o 15 me 4 ko 60. Me tahuri \frac{4}{15} me \frac{1}{4} ki te hautau me te tautūnga 60.

$$\frac{16}{60}+\frac{15}{60}$$

Tā te mea he rite te tauraro o \frac{16}{60} me \frac{15}{60}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{16+15}{60}$$

Tāpirihia te 16 ki te 15, ka 31.

$$\frac{31}{60}$$

Tauwehe

$$\frac{31}{2 ^ {2} \cdot 3 \cdot 5} = 0.5166666666666667$$
