Whakaoti i te 41/2*32/5

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

Aromātai

$$\frac{153}{10}=15.3$$

Ngā Upane Otinga

Whakareatia te 4 ki te 2, ka 8.

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

Tāpirihia te 8 ki te 1, ka 9.

$$\frac{9}{2}\times \frac{3\times 5+2}{5}$$

Whakareatia te 3 ki te 5, ka 15.

$$\frac{9}{2}\times \frac{15+2}{5}$$

Tāpirihia te 15 ki te 2, ka 17.

$$\frac{9}{2}\times \frac{17}{5}$$

Me whakarea te \frac{9}{2} ki te \frac{17}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{9\times 17}{2\times 5}$$

Mahia ngā whakarea i roto i te hautanga \frac{9\times 17}{2\times 5}.

$$\frac{153}{10}$$

Tauwehe

$$\frac{3 ^ {2} \cdot 17}{2 \cdot 5} = 15\frac{3}{10} = 15.3$$
