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

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

Aromātai

$$\frac{3}{8}=0.375$$

Ngā Upane Otinga

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

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

Tā te mea he rite te tauraro o \frac{2}{4} me \frac{1}{4}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

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

Tāpirihia te 2 ki te 1, ka 3.

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

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

$$\frac{6}{8}-\frac{3}{8}$$

Tā te mea he rite te tauraro o \frac{6}{8} me \frac{3}{8}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{6-3}{8}$$

Tangohia te 3 i te 6, ka 3.

$$\frac{3}{8}$$

Tauwehe

$$\frac{3}{2 ^ {3}} = 0.375$$
