Whakaoti i te 32/5div21/2

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

Aromātai

$$\frac{34}{25}=1.36$$

Ngā Upane Otinga

Whakawehe \frac{3\times 5+2}{5} ki te \frac{2\times 2+1}{2} mā te whakarea \frac{3\times 5+2}{5} ki te tau huripoki o \frac{2\times 2+1}{2}.

$$\frac{\left(3\times 5+2\right)\times 2}{5\left(2\times 2+1\right)}$$

Whakareatia te 3 ki te 5, ka 15.

$$\frac{\left(15+2\right)\times 2}{5\left(2\times 2+1\right)}$$

Tāpirihia te 15 ki te 2, ka 17.

$$\frac{17\times 2}{5\left(2\times 2+1\right)}$$

Whakareatia te 17 ki te 2, ka 34.

$$\frac{34}{5\left(2\times 2+1\right)}$$

Whakareatia te 2 ki te 2, ka 4.

$$\frac{34}{5\left(4+1\right)}$$

Tāpirihia te 4 ki te 1, ka 5.

$$\frac{34}{5\times 5}$$

Whakareatia te 5 ki te 5, ka 25.

$$\frac{34}{25}$$

Tauwehe

$$\frac{2 \cdot 17}{5 ^ {2}} = 1\frac{9}{25} = 1.36$$
