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

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

Aromātai

$$\frac{7}{4}=1.75$$

Ngā Upane Otinga

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

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

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

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

Tangohia te 4 i te 1, ka -3.

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

Ko te maha noa iti rawa atu o 4 me 2 ko 4. Me tahuri -\frac{3}{4} me \frac{1}{2} ki te hautau me te tautūnga 4.

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

Tā te mea he rite te tauraro o -\frac{3}{4} me \frac{2}{4}, me tango rāua mā te tango i ō raua taurunga.

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

Tangohia te 2 i te -3, ka -5.

$$-\frac{5}{4}+3$$

Me tahuri te 3 ki te hautau \frac{12}{4}.

$$-\frac{5}{4}+\frac{12}{4}$$

Tā te mea he rite te tauraro o -\frac{5}{4} me \frac{12}{4}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-5+12}{4}$$

Tāpirihia te -5 ki te 12, ka 7.

$$\frac{7}{4}$$

Tauwehe

$$\frac{7}{2 ^ {2}} = 1\frac{3}{4} = 1.75$$
