Whakaoti i te (8+3/4)div41/5=

$$( 8 + \frac { 3 } { 4 } ) \div 4 \frac { 1 } { 5 } =$$

Aromātai

$$\frac{25}{12}\approx 2.083333333$$

Ngā Upane Otinga

Me tahuri te 8 ki te hautau \frac{32}{4}.

$$\frac{\frac{32}{4}+\frac{3}{4}}{\frac{4\times 5+1}{5}}$$

Tā te mea he rite te tauraro o \frac{32}{4} me \frac{3}{4}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{\frac{32+3}{4}}{\frac{4\times 5+1}{5}}$$

Tāpirihia te 32 ki te 3, ka 35.

$$\frac{\frac{35}{4}}{\frac{4\times 5+1}{5}}$$

Whakareatia te 4 ki te 5, ka 20.

$$\frac{\frac{35}{4}}{\frac{20+1}{5}}$$

Tāpirihia te 20 ki te 1, ka 21.

$$\frac{\frac{35}{4}}{\frac{21}{5}}$$

Whakawehe \frac{35}{4} ki te \frac{21}{5} mā te whakarea \frac{35}{4} ki te tau huripoki o \frac{21}{5}.

$$\frac{35}{4}\times \frac{5}{21}$$

Me whakarea te \frac{35}{4} ki te \frac{5}{21} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{35\times 5}{4\times 21}$$

Mahia ngā whakarea i roto i te hautanga \frac{35\times 5}{4\times 21}.

$$\frac{175}{84}$$

Whakahekea te hautanga \frac{175}{84} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 7.

$$\frac{25}{12}$$

Tauwehe

$$\frac{5 ^ {2}}{2 ^ {2} \cdot 3} = 2\frac{1}{12} = 2.0833333333333335$$
