Ngā Upane Otinga

Whakawehe \frac{1\times 2+1}{2} ki te \frac{3\times 5+4}{5} mā te whakarea \frac{1\times 2+1}{2} ki te tau huripoki o \frac{3\times 5+4}{5}.

$$\frac{\left(1\times 2+1\right)\times 5}{2\left(3\times 5+4\right)}$$

Whakareatia te 1 ki te 2, ka 2.

$$\frac{\left(2+1\right)\times 5}{2\left(3\times 5+4\right)}$$

Tāpirihia te 2 ki te 1, ka 3.

$$\frac{3\times 5}{2\left(3\times 5+4\right)}$$

Whakareatia te 3 ki te 5, ka 15.

$$\frac{15}{2\left(3\times 5+4\right)}$$

Whakareatia te 3 ki te 5, ka 15.

$$\frac{15}{2\left(15+4\right)}$$

Tāpirihia te 15 ki te 4, ka 19.

$$\frac{15}{2\times 19}$$

Whakareatia te 2 ki te 19, ka 38.

$$\frac{15}{38}$$

Tauwehe

$$\frac{3 \cdot 5}{2 \cdot 19} = 0.39473684210526316$$
