Whakaoti i te 1/2+23/4-3/8

$$\frac { 1 } { 2 } + 2 \frac { 3 } { 4 } - \frac { 3 } { 8 }$$

Aromātai

$$\frac{23}{8}=2.875$$

Ngā Upane Otinga

Whakareatia te 2 ki te 4, ka 8.

$$\frac{1}{2}+\frac{8+3}{4}-\frac{3}{8}$$

Tāpirihia te 8 ki te 3, ka 11.

$$\frac{1}{2}+\frac{11}{4}-\frac{3}{8}$$

Ko te maha noa iti rawa atu o 2 me 4 ko 4. Me tahuri \frac{1}{2} me \frac{11}{4} ki te hautau me te tautūnga 4.

$$\frac{2}{4}+\frac{11}{4}-\frac{3}{8}$$

Tā te mea he rite te tauraro o \frac{2}{4} me \frac{11}{4}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{2+11}{4}-\frac{3}{8}$$

Tāpirihia te 2 ki te 11, ka 13.

$$\frac{13}{4}-\frac{3}{8}$$

Ko te maha noa iti rawa atu o 4 me 8 ko 8. Me tahuri \frac{13}{4} me \frac{3}{8} ki te hautau me te tautūnga 8.

$$\frac{26}{8}-\frac{3}{8}$$

Tā te mea he rite te tauraro o \frac{26}{8} me \frac{3}{8}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{26-3}{8}$$

Tangohia te 3 i te 26, ka 23.

$$\frac{23}{8}$$

Tauwehe

$$\frac{23}{2 ^ {3}} = 2\frac{7}{8} = 2.875$$
