Ngā Upane Otinga

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

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

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

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

Tāpirihia te 1 ki te 2, ka 3.

$$\frac{2\times 3}{1+2\times 4}$$

Whakareatia te 2 ki te 3, ka 6.

$$\frac{6}{1+2\times 4}$$

Whakareatia te 2 ki te 4, ka 8.

$$\frac{6}{1+8}$$

Tāpirihia te 1 ki te 8, ka 9.

$$\frac{6}{9}$$

Whakahekea te hautanga \frac{6}{9} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$\frac{2}{3}$$

Tauwehe

$$\frac{2}{3} = 0.6666666666666666$$
