Whakaoti i te 2(154+3)/3-(154-3)/4

$$\frac { 2 ( 154 + 3 ) } { 3 } - \frac { ( 154 - 3 ) } { 4 }$$

Aromātai

$$\frac{803}{12}\approx 66.916666667$$

Ngā Upane Otinga

Tāpirihia te 154 ki te 3, ka 157.

$$\frac{2\times 157}{3}-\frac{154-3}{4}$$

Whakareatia te 2 ki te 157, ka 314.

$$\frac{314}{3}-\frac{154-3}{4}$$

Tangohia te 3 i te 154, ka 151.

$$\frac{314}{3}-\frac{151}{4}$$

Ko te maha noa iti rawa atu o 3 me 4 ko 12. Me tahuri \frac{314}{3} me \frac{151}{4} ki te hautau me te tautūnga 12.

$$\frac{1256}{12}-\frac{453}{12}$$

Tā te mea he rite te tauraro o \frac{1256}{12} me \frac{453}{12}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{1256-453}{12}$$

Tangohia te 453 i te 1256, ka 803.

$$\frac{803}{12}$$

Tauwehe

$$\frac{11 \cdot 73}{2 ^ {2} \cdot 3} = 66\frac{11}{12} = 66.91666666666667$$
