Whakaoti i te 21/4div2/3

$$2 \frac { 1 } { 4 } \div \frac { 2 } { 3 }$$

Aromātai

$$\frac{27}{8}=3.375$$

Ngā Upane Otinga

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

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

Whakareatia te 2 ki te 4, ka 8.

$$\frac{\left(8+1\right)\times 3}{4\times 2}$$

Tāpirihia te 8 ki te 1, ka 9.

$$\frac{9\times 3}{4\times 2}$$

Whakareatia te 9 ki te 3, ka 27.

$$\frac{27}{4\times 2}$$

Whakareatia te 4 ki te 2, ka 8.

$$\frac{27}{8}$$

Tauwehe

$$\frac{3 ^ {3}}{2 ^ {3}} = 3\frac{3}{8} = 3.375$$
