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

Aromātai

$$\frac{189}{50}=3.78$$

Ngā Upane Otinga

Whakareatia te 1 ki te 5, ka 5.

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

Tāpirihia te 5 ki te 4, ka 9.

$$\frac{9}{5}\times \frac{1\times 5+1}{5}\times \frac{1\times 4+3}{4}$$

Whakareatia te 1 ki te 5, ka 5.

$$\frac{9}{5}\times \frac{5+1}{5}\times \frac{1\times 4+3}{4}$$

Tāpirihia te 5 ki te 1, ka 6.

$$\frac{9}{5}\times \frac{6}{5}\times \frac{1\times 4+3}{4}$$

Me whakarea te \frac{9}{5} ki te \frac{6}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{9\times 6}{5\times 5}\times \frac{1\times 4+3}{4}$$

Mahia ngā whakarea i roto i te hautanga \frac{9\times 6}{5\times 5}.

$$\frac{54}{25}\times \frac{1\times 4+3}{4}$$

Whakareatia te 1 ki te 4, ka 4.

$$\frac{54}{25}\times \frac{4+3}{4}$$

Tāpirihia te 4 ki te 3, ka 7.

$$\frac{54}{25}\times \frac{7}{4}$$

Me whakarea te \frac{54}{25} ki te \frac{7}{4} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{54\times 7}{25\times 4}$$

Mahia ngā whakarea i roto i te hautanga \frac{54\times 7}{25\times 4}.

$$\frac{378}{100}$$

Whakahekea te hautanga \frac{378}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{189}{50}$$

Tauwehe

$$\frac{3 ^ {3} \cdot 7}{2 \cdot 5 ^ {2}} = 3\frac{39}{50} = 3.78$$
