Whakaoti i te [(13-111/2):0.03]*0.026=

$$[ ( 13 - 11 \frac { 1 } { 2 } ) : 0.03 ] \cdot 0.026 =$$

Aromātai

$$1.3$$

Ngā Upane Otinga

Whakareatia te 11 ki te 2, ka 22.

$$\frac{13-\frac{22+1}{2}}{0.03}\times 0.026$$

Tāpirihia te 22 ki te 1, ka 23.

$$\frac{13-\frac{23}{2}}{0.03}\times 0.026$$

Me tahuri te 13 ki te hautau \frac{26}{2}.

$$\frac{\frac{26}{2}-\frac{23}{2}}{0.03}\times 0.026$$

Tā te mea he rite te tauraro o \frac{26}{2} me \frac{23}{2}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{\frac{26-23}{2}}{0.03}\times 0.026$$

Tangohia te 23 i te 26, ka 3.

$$\frac{\frac{3}{2}}{0.03}\times 0.026$$

Tuhia te \frac{\frac{3}{2}}{0.03} hei hautanga kotahi.

$$\frac{3}{2\times 0.03}\times 0.026$$

Whakareatia te 2 ki te 0.03, ka 0.06.

$$\frac{3}{0.06}\times 0.026$$

Whakarohaina te \frac{3}{0.06} mā te whakarea i te taurunga me te tauraro ki te 100.

$$\frac{300}{6}\times 0.026$$

Whakawehea te 300 ki te 6, kia riro ko 50.

$$50\times 0.026$$

Whakareatia te 50 ki te 0.026, ka 1.3.

$$1.3$$

Tauwehe

$$\frac{13}{2 \cdot 5} = 1\frac{3}{10} = 1.3$$
