Whakaoti i te 3/4+125div11/2

$$\frac { 3 } { 4 } + 125 \div 1 \frac { 1 } { 2 }$$

Aromātai

$$\frac{1009}{12}\approx 84.083333333$$

Ngā Upane Otinga

Whakawehe 125 ki te \frac{1\times 2+1}{2} mā te whakarea 125 ki te tau huripoki o \frac{1\times 2+1}{2}.

$$\frac{3}{4}+\frac{125\times 2}{1\times 2+1}$$

Whakareatia te 125 ki te 2, ka 250.

$$\frac{3}{4}+\frac{250}{1\times 2+1}$$

Whakareatia te 1 ki te 2, ka 2.

$$\frac{3}{4}+\frac{250}{2+1}$$

Tāpirihia te 2 ki te 1, ka 3.

$$\frac{3}{4}+\frac{250}{3}$$

Ko te maha noa iti rawa atu o 4 me 3 ko 12. Me tahuri \frac{3}{4} me \frac{250}{3} ki te hautau me te tautūnga 12.

$$\frac{9}{12}+\frac{1000}{12}$$

Tā te mea he rite te tauraro o \frac{9}{12} me \frac{1000}{12}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{9+1000}{12}$$

Tāpirihia te 9 ki te 1000, ka 1009.

$$\frac{1009}{12}$$

Tauwehe

$$\frac{1009}{2 ^ {2} \cdot 3} = 84\frac{1}{12} = 84.08333333333333$$
