Ngā Upane Otinga

Whakawehe \frac{2\times 8+1}{8} ki te \frac{1\times 2+1}{2} mā te whakarea \frac{2\times 8+1}{8} ki te tau huripoki o \frac{1\times 2+1}{2}.

$$\frac{\left(2\times 8+1\right)\times 2}{8\left(1\times 2+1\right)}$$

Me whakakore tahi te 2 i te taurunga me te tauraro.

$$\frac{1+2\times 8}{4\left(1+2\right)}$$

Whakareatia te 2 ki te 8, ka 16.

$$\frac{1+16}{4\left(1+2\right)}$$

Tāpirihia te 1 ki te 16, ka 17.

$$\frac{17}{4\left(1+2\right)}$$

Tāpirihia te 1 ki te 2, ka 3.

$$\frac{17}{4\times 3}$$

Whakareatia te 4 ki te 3, ka 12.

$$\frac{17}{12}$$

Tauwehe

$$\frac{17}{2 ^ {2} \cdot 3} = 1\frac{5}{12} = 1.4166666666666667$$
