Whakaoti i te 1/2div5/8+1/4*3/5

$$\frac { 1 } { 2 } \div \frac { 5 } { 8 } + \frac { 1 } { 4 } \times \frac { 3 } { 5 }$$

Aromātai

$$\frac{19}{20}=0.95$$

Ngā Upane Otinga

Whakawehe \frac{1}{2} ki te \frac{5}{8} mā te whakarea \frac{1}{2} ki te tau huripoki o \frac{5}{8}.

$$\frac{1}{2}\times \frac{8}{5}+\frac{1}{4}\times \frac{3}{5}$$

Me whakarea te \frac{1}{2} ki te \frac{8}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{1\times 8}{2\times 5}+\frac{1}{4}\times \frac{3}{5}$$

Mahia ngā whakarea i roto i te hautanga \frac{1\times 8}{2\times 5}.

$$\frac{8}{10}+\frac{1}{4}\times \frac{3}{5}$$

Whakahekea te hautanga \frac{8}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{4}{5}+\frac{1}{4}\times \frac{3}{5}$$

Me whakarea te \frac{1}{4} ki te \frac{3}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{4}{5}+\frac{1\times 3}{4\times 5}$$

Mahia ngā whakarea i roto i te hautanga \frac{1\times 3}{4\times 5}.

$$\frac{4}{5}+\frac{3}{20}$$

Ko te maha noa iti rawa atu o 5 me 20 ko 20. Me tahuri \frac{4}{5} me \frac{3}{20} ki te hautau me te tautūnga 20.

$$\frac{16}{20}+\frac{3}{20}$$

Tā te mea he rite te tauraro o \frac{16}{20} me \frac{3}{20}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{16+3}{20}$$

Tāpirihia te 16 ki te 3, ka 19.

$$\frac{19}{20}$$

Tauwehe

$$\frac{19}{2 ^ {2} \cdot 5} = 0.95$$
