Aromātai

$$\frac{37}{26}\approx 1.423076923$$

Ngā Upane Otinga

Whakawehe \frac{3\times 12+1}{12} ki te \frac{2\times 6+1}{6} mā te whakarea \frac{3\times 12+1}{12} ki te tau huripoki o \frac{2\times 6+1}{6}.

$$\frac{\left(3\times 12+1\right)\times 6}{12\left(2\times 6+1\right)}$$

Me whakakore tahi te 6 i te taurunga me te tauraro.

$$\frac{1+3\times 12}{2\left(1+2\times 6\right)}$$

Whakareatia te 3 ki te 12, ka 36.

$$\frac{1+36}{2\left(1+2\times 6\right)}$$

Tāpirihia te 1 ki te 36, ka 37.

$$\frac{37}{2\left(1+2\times 6\right)}$$

Whakareatia te 2 ki te 6, ka 12.

$$\frac{37}{2\left(1+12\right)}$$

Tāpirihia te 1 ki te 12, ka 13.

$$\frac{37}{2\times 13}$$

Whakareatia te 2 ki te 13, ka 26.

$$\frac{37}{26}$$

Tauwehe

$$\frac{37}{2 \cdot 13} = 1\frac{11}{26} = 1.4230769230769231$$
