Whakaoti i te 41/2div24/7

$$4 \frac { 1 } { 2 } \div 2 \frac { 4 } { 7 }$$

Aromātai

$$\frac{7}{4}=1.75$$

Ngā Upane Otinga

Whakawehe \frac{4\times 2+1}{2} ki te \frac{2\times 7+4}{7} mā te whakarea \frac{4\times 2+1}{2} ki te tau huripoki o \frac{2\times 7+4}{7}.

$$\frac{\left(4\times 2+1\right)\times 7}{2\left(2\times 7+4\right)}$$

Whakareatia te 4 ki te 2, ka 8.

$$\frac{\left(8+1\right)\times 7}{2\left(2\times 7+4\right)}$$

Tāpirihia te 8 ki te 1, ka 9.

$$\frac{9\times 7}{2\left(2\times 7+4\right)}$$

Whakareatia te 9 ki te 7, ka 63.

$$\frac{63}{2\left(2\times 7+4\right)}$$

Whakareatia te 2 ki te 7, ka 14.

$$\frac{63}{2\left(14+4\right)}$$

Tāpirihia te 14 ki te 4, ka 18.

$$\frac{63}{2\times 18}$$

Whakareatia te 2 ki te 18, ka 36.

$$\frac{63}{36}$$

Whakahekea te hautanga \frac{63}{36} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 9.

$$\frac{7}{4}$$

Tauwehe

$$\frac{7}{2 ^ {2}} = 1\frac{3}{4} = 1.75$$
