Ngā Upane Otinga

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

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

Whakareatia te 4 ki te 5, ka 20.

$$\frac{\left(20+2\right)\times 2}{5\left(4\times 2+1\right)}$$

Tāpirihia te 20 ki te 2, ka 22.

$$\frac{22\times 2}{5\left(4\times 2+1\right)}$$

Whakareatia te 22 ki te 2, ka 44.

$$\frac{44}{5\left(4\times 2+1\right)}$$

Whakareatia te 4 ki te 2, ka 8.

$$\frac{44}{5\left(8+1\right)}$$

Tāpirihia te 8 ki te 1, ka 9.

$$\frac{44}{5\times 9}$$

Whakareatia te 5 ki te 9, ka 45.

$$\frac{44}{45}$$

Tauwehe

$$\frac{2 ^ {2} \cdot 11}{3 ^ {2} \cdot 5} = 0.9777777777777777$$
