Whakaoti i te 3/2-21/4+1?

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

Aromātai

$$\frac{1}{4}=0.25$$

Ngā Upane Otinga

Whakareatia te 2 ki te 4, ka 8.

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

Tāpirihia te 8 ki te 1, ka 9.

$$\frac{3}{2}-\frac{9}{4}+1$$

Ko te maha noa iti rawa atu o 2 me 4 ko 4. Me tahuri \frac{3}{2} me \frac{9}{4} ki te hautau me te tautūnga 4.

$$\frac{6}{4}-\frac{9}{4}+1$$

Tā te mea he rite te tauraro o \frac{6}{4} me \frac{9}{4}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{6-9}{4}+1$$

Tangohia te 9 i te 6, ka -3.

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

Me tahuri te 1 ki te hautau \frac{4}{4}.

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

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

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

Tāpirihia te -3 ki te 4, ka 1.

$$\frac{1}{4}$$

Tauwehe

$$\frac{1}{2 ^ {2}} = 0.25$$
