Whakaoti i te (51/4+4)+11/2

$$( \frac { 51 } { 4 } + 4 ) + 1 \frac { 1 } { 2 }$$

Aromātai

$$\frac{73}{4}=18.25$$

Ngā Upane Otinga

Me tahuri te 4 ki te hautau \frac{16}{4}.

$$\frac{51}{4}+\frac{16}{4}+\frac{1\times 2+1}{2}$$

Tā te mea he rite te tauraro o \frac{51}{4} me \frac{16}{4}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{51+16}{4}+\frac{1\times 2+1}{2}$$

Tāpirihia te 51 ki te 16, ka 67.

$$\frac{67}{4}+\frac{1\times 2+1}{2}$$

Whakareatia te 1 ki te 2, ka 2.

$$\frac{67}{4}+\frac{2+1}{2}$$

Tāpirihia te 2 ki te 1, ka 3.

$$\frac{67}{4}+\frac{3}{2}$$

Ko te maha noa iti rawa atu o 4 me 2 ko 4. Me tahuri \frac{67}{4} me \frac{3}{2} ki te hautau me te tautūnga 4.

$$\frac{67}{4}+\frac{6}{4}$$

Tā te mea he rite te tauraro o \frac{67}{4} me \frac{6}{4}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{67+6}{4}$$

Tāpirihia te 67 ki te 6, ka 73.

$$\frac{73}{4}$$

Tauwehe

$$\frac{73}{2 ^ {2}} = 18\frac{1}{4} = 18.25$$
