Ngā Upane Otinga

Me whakakore tahi te 2\times 5 i te taurunga me te tauraro.

$$\frac{3\times 14\times \frac{1}{4}}{9.2\times \frac{1}{2}}$$

Whakareatia te 3 ki te 14, ka 42.

$$\frac{42\times \frac{1}{4}}{9.2\times \frac{1}{2}}$$

Whakareatia te 42 ki te \frac{1}{4}, ka \frac{21}{2}.

$$\frac{\frac{21}{2}}{9.2\times \frac{1}{2}}$$

Whakareatia te 9.2 ki te \frac{1}{2}, ka \frac{23}{5}.

$$\frac{\frac{21}{2}}{\frac{23}{5}}$$

Whakawehe \frac{21}{2} ki te \frac{23}{5} mā te whakarea \frac{21}{2} ki te tau huripoki o \frac{23}{5}.

$$\frac{21}{2}\times \frac{5}{23}$$

Whakareatia te \frac{21}{2} ki te \frac{5}{23}, ka \frac{105}{46}.

$$\frac{105}{46}$$

Tauwehe

$$\frac{3 \cdot 5 \cdot 7}{2 \cdot 23} = 2\frac{13}{46} = 2.282608695652174$$
