Whakaoti i te 1/2*2+1/3*4+5*1/4

$$\frac { 1 } { 2 } \cdot 2 + \frac { 1 } { 3 } \cdot 4 + 5 \cdot \frac { 1 } { 4 }$$

Aromātai

$$\frac{43}{12}\approx 3.583333333$$

Ngā Upane Otinga

Me whakakore te 2 me te 2.

$$1+\frac{1}{3}\times 4+5\times \frac{1}{4}$$

Whakareatia te \frac{1}{3} ki te 4, ka \frac{4}{3}.

$$1+\frac{4}{3}+5\times \frac{1}{4}$$

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

$$\frac{3}{3}+\frac{4}{3}+5\times \frac{1}{4}$$

Tā te mea he rite te tauraro o \frac{3}{3} me \frac{4}{3}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{3+4}{3}+5\times \frac{1}{4}$$

Tāpirihia te 3 ki te 4, ka 7.

$$\frac{7}{3}+5\times \frac{1}{4}$$

Whakareatia te 5 ki te \frac{1}{4}, ka \frac{5}{4}.

$$\frac{7}{3}+\frac{5}{4}$$

Ko te maha noa iti rawa atu o 3 me 4 ko 12. Me tahuri \frac{7}{3} me \frac{5}{4} ki te hautau me te tautūnga 12.

$$\frac{28}{12}+\frac{15}{12}$$

Tā te mea he rite te tauraro o \frac{28}{12} me \frac{15}{12}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{28+15}{12}$$

Tāpirihia te 28 ki te 15, ka 43.

$$\frac{43}{12}$$

Tauwehe

$$\frac{43}{2 ^ {2} \cdot 3} = 3\frac{7}{12} = 3.5833333333333335$$
