Whakaoti i te 11/5*32/5

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

Aromātai

$$\frac{102}{25}=4.08$$

Ngā Upane Otinga

Whakareatia te 1 ki te 5, ka 5.

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

Tāpirihia te 5 ki te 1, ka 6.

$$\frac{6}{5}\times \frac{3\times 5+2}{5}$$

Whakareatia te 3 ki te 5, ka 15.

$$\frac{6}{5}\times \frac{15+2}{5}$$

Tāpirihia te 15 ki te 2, ka 17.

$$\frac{6}{5}\times \frac{17}{5}$$

Me whakarea te \frac{6}{5} ki te \frac{17}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{6\times 17}{5\times 5}$$

Mahia ngā whakarea i roto i te hautanga \frac{6\times 17}{5\times 5}.

$$\frac{102}{25}$$

Tauwehe

$$\frac{2 \cdot 3 \cdot 17}{5 ^ {2}} = 4\frac{2}{25} = 4.08$$
