Whakaoti i te 2/3div1/4*4-2^2

$$\frac { 2 } { 3 } \div \frac { 1 } { 4 } \times 4 - 2 ^ { 2 }$$

Aromātai

$$\frac{20}{3}\approx 6.666666667$$

Ngā Upane Otinga

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

$$\frac{2}{3}\times 4\times 4-2^{2}$$

Tuhia te \frac{2}{3}\times 4 hei hautanga kotahi.

$$\frac{2\times 4}{3}\times 4-2^{2}$$

Whakareatia te 2 ki te 4, ka 8.

$$\frac{8}{3}\times 4-2^{2}$$

Tuhia te \frac{8}{3}\times 4 hei hautanga kotahi.

$$\frac{8\times 4}{3}-2^{2}$$

Whakareatia te 8 ki te 4, ka 32.

$$\frac{32}{3}-2^{2}$$

Tātaihia te 2 mā te pū o 2, kia riro ko 4.

$$\frac{32}{3}-4$$

Me tahuri te 4 ki te hautau \frac{12}{3}.

$$\frac{32}{3}-\frac{12}{3}$$

Tā te mea he rite te tauraro o \frac{32}{3} me \frac{12}{3}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{32-12}{3}$$

Tangohia te 12 i te 32, ka 20.

$$\frac{20}{3}$$

Tauwehe

$$\frac{2 ^ {2} \cdot 5}{3} = 6\frac{2}{3} = 6.666666666666667$$
