Aromātai

$$\frac{2}{3}\approx 0.666666667$$

Ngā Upane Otinga

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

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

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

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

Whakareatia te 2 ki te 2, ka 4.

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

Tāpirihia te 1 ki te 4, ka 5.

$$\frac{2\times 5}{3+3\times 4}$$

Whakareatia te 2 ki te 5, ka 10.

$$\frac{10}{3+3\times 4}$$

Whakareatia te 3 ki te 4, ka 12.

$$\frac{10}{3+12}$$

Tāpirihia te 3 ki te 12, ka 15.

$$\frac{10}{15}$$

Whakahekea te hautanga \frac{10}{15} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

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

Tauwehe

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