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

Aromātai

$$\frac{5}{4}=1.25$$

Ngā Upane Otinga

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

$$\frac{9}{4}-\frac{12}{4}+2$$

Tā te mea he rite te tauraro o \frac{9}{4} me \frac{12}{4}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{9-12}{4}+2$$

Tangohia te 12 i te 9, ka -3.

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

Me tahuri te 2 ki te hautau \frac{8}{4}.

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

Tā te mea he rite te tauraro o -\frac{3}{4} me \frac{8}{4}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

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

Tāpirihia te -3 ki te 8, ka 5.

$$\frac{5}{4}$$

Tauwehe

$$\frac{5}{2 ^ {2}} = 1\frac{1}{4} = 1.25$$
