Whakaoti i te 11/2*34/5

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

Aromātai

$$\frac{57}{10}=5.7$$

Ngā Upane Otinga

Whakareatia te 1 ki te 2, ka 2.

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

Tāpirihia te 2 ki te 1, ka 3.

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

Whakareatia te 3 ki te 5, ka 15.

$$\frac{3}{2}\times \frac{15+4}{5}$$

Tāpirihia te 15 ki te 4, ka 19.

$$\frac{3}{2}\times \frac{19}{5}$$

Me whakarea te \frac{3}{2} ki te \frac{19}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{3\times 19}{2\times 5}$$

Mahia ngā whakarea i roto i te hautanga \frac{3\times 19}{2\times 5}.

$$\frac{57}{10}$$

Tauwehe

$$\frac{3 \cdot 19}{2 \cdot 5} = 5\frac{7}{10} = 5.7$$
