Whakaoti i te 1.9/3+9-1/4=

$$\frac { 1.9 } { 3 } + \frac { 9 - 1 } { 4 } =$$

Aromātai

$$\frac{79}{30}\approx 2.633333333$$

Ngā Upane Otinga

Whakarohaina te \frac{1.9}{3} mā te whakarea i te taurunga me te tauraro ki te 10.

$$\frac{19}{30}+\frac{9-1}{4}$$

Tangohia te 1 i te 9, ka 8.

$$\frac{19}{30}+\frac{8}{4}$$

Whakawehea te 8 ki te 4, kia riro ko 2.

$$\frac{19}{30}+2$$

Me tahuri te 2 ki te hautau \frac{60}{30}.

$$\frac{19}{30}+\frac{60}{30}$$

Tā te mea he rite te tauraro o \frac{19}{30} me \frac{60}{30}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{19+60}{30}$$

Tāpirihia te 19 ki te 60, ka 79.

$$\frac{79}{30}$$

Tauwehe

$$\frac{79}{2 \cdot 3 \cdot 5} = 2\frac{19}{30} = 2.6333333333333333$$
