$$4 \frac { 3 } { 8 } \div ( 5 \frac { 21 } { 4 } \times \frac { 4 } { 5 } )$$

Aromātai

$$\frac{175}{328}\approx 0.533536585$$

Ngā Upane Otinga

Whakareatia te 4 ki te 8, ka 32.

$$\frac{\frac{32+3}{8}}{\frac{5\times 4+21}{4}\times \frac{4}{5}}$$

Tāpirihia te 32 ki te 3, ka 35.

$$\frac{\frac{35}{8}}{\frac{5\times 4+21}{4}\times \frac{4}{5}}$$

Whakareatia te 5 ki te 4, ka 20.

$$\frac{\frac{35}{8}}{\frac{20+21}{4}\times \frac{4}{5}}$$

Tāpirihia te 20 ki te 21, ka 41.

$$\frac{\frac{35}{8}}{\frac{41}{4}\times \frac{4}{5}}$$

Me whakarea te \frac{41}{4} ki te \frac{4}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{\frac{35}{8}}{\frac{41\times 4}{4\times 5}}$$

Me whakakore tahi te 4 i te taurunga me te tauraro.

$$\frac{\frac{35}{8}}{\frac{41}{5}}$$

Whakawehe \frac{35}{8} ki te \frac{41}{5} mā te whakarea \frac{35}{8} ki te tau huripoki o \frac{41}{5}.

$$\frac{35}{8}\times \frac{5}{41}$$

Me whakarea te \frac{35}{8} ki te \frac{5}{41} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{35\times 5}{8\times 41}$$

Mahia ngā whakarea i roto i te hautanga \frac{35\times 5}{8\times 41}.

$$\frac{175}{328}$$

Tauwehe

$$\frac{5 ^ {2} \cdot 7}{2 ^ {3} \cdot 41} = 0.5335365853658537$$
