Whakaoti i te 1+20:5*7/3*7-2*12/2=?

$$1 + 20 : 5 \times 7 / 3 * 7 - 2 \times 12 / 2 = ?$$

Aromātai

$$\frac{163}{3}\approx 54.333333333$$

Ngā Upane Otinga

Whakawehea te 20 ki te 5, kia riro ko 4.

$$1+4\times \frac{7}{3}\times 7-2\times \frac{12}{2}$$

Tuhia te 4\times \frac{7}{3} hei hautanga kotahi.

$$1+\frac{4\times 7}{3}\times 7-2\times \frac{12}{2}$$

Whakareatia te 4 ki te 7, ka 28.

$$1+\frac{28}{3}\times 7-2\times \frac{12}{2}$$

Tuhia te \frac{28}{3}\times 7 hei hautanga kotahi.

$$1+\frac{28\times 7}{3}-2\times \frac{12}{2}$$

Whakareatia te 28 ki te 7, ka 196.

$$1+\frac{196}{3}-2\times \frac{12}{2}$$

Me tahuri te 1 ki te hautau \frac{3}{3}.

$$\frac{3}{3}+\frac{196}{3}-2\times \frac{12}{2}$$

Tā te mea he rite te tauraro o \frac{3}{3} me \frac{196}{3}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{3+196}{3}-2\times \frac{12}{2}$$

Tāpirihia te 3 ki te 196, ka 199.

$$\frac{199}{3}-2\times \frac{12}{2}$$

Whakawehea te 12 ki te 2, kia riro ko 6.

$$\frac{199}{3}-2\times 6$$

Whakareatia te 2 ki te 6, ka 12.

$$\frac{199}{3}-12$$

Me tahuri te 12 ki te hautau \frac{36}{3}.

$$\frac{199}{3}-\frac{36}{3}$$

Tā te mea he rite te tauraro o \frac{199}{3} me \frac{36}{3}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{199-36}{3}$$

Tangohia te 36 i te 199, ka 163.

$$\frac{163}{3}$$

Tauwehe

$$\frac{163}{3} = 54\frac{1}{3} = 54.333333333333336$$
