Whakaoti i te (7/8+5/3)*2/8

$$( \frac { 7 } { 8 } + \frac { 5 } { 3 } ) \cdot \frac { 2 } { 8 }$$

Aromātai

$$\frac{61}{96}\approx 0.635416667$$

Ngā Upane Otinga

Ko te maha noa iti rawa atu o 8 me 3 ko 24. Me tahuri \frac{7}{8} me \frac{5}{3} ki te hautau me te tautūnga 24.

$$\left(\frac{21}{24}+\frac{40}{24}\right)\times \frac{2}{8}$$

Tā te mea he rite te tauraro o \frac{21}{24} me \frac{40}{24}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{21+40}{24}\times \frac{2}{8}$$

Tāpirihia te 21 ki te 40, ka 61.

$$\frac{61}{24}\times \frac{2}{8}$$

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

$$\frac{61}{24}\times \frac{1}{4}$$

Me whakarea te \frac{61}{24} ki te \frac{1}{4} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{61\times 1}{24\times 4}$$

Mahia ngā whakarea i roto i te hautanga \frac{61\times 1}{24\times 4}.

$$\frac{61}{96}$$

Tauwehe

$$\frac{61}{2 ^ {5} \cdot 3} = 0.6354166666666666$$
