Whakaoti i te 2/11*(21/2+1/4)

$$\frac { 2 } { 11 } \times ( 2 \frac { 1 } { 2 } + \frac { 1 } { 4 } )$$

Aromātai

$$\frac{1}{2}=0.5$$

Ngā Upane Otinga

Whakareatia te 2 ki te 2, ka 4.

$$\frac{2}{11}\left(\frac{4+1}{2}+\frac{1}{4}\right)$$

Tāpirihia te 4 ki te 1, ka 5.

$$\frac{2}{11}\left(\frac{5}{2}+\frac{1}{4}\right)$$

Ko te maha noa iti rawa atu o 2 me 4 ko 4. Me tahuri \frac{5}{2} me \frac{1}{4} ki te hautau me te tautūnga 4.

$$\frac{2}{11}\left(\frac{10}{4}+\frac{1}{4}\right)$$

Tā te mea he rite te tauraro o \frac{10}{4} me \frac{1}{4}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{2}{11}\times \frac{10+1}{4}$$

Tāpirihia te 10 ki te 1, ka 11.

$$\frac{2}{11}\times \frac{11}{4}$$

Me whakarea te \frac{2}{11} ki te \frac{11}{4} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{2\times 11}{11\times 4}$$

Me whakakore tahi te 11 i te taurunga me te tauraro.

$$\frac{2}{4}$$

Whakahekea te hautanga \frac{2}{4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{1}{2}$$

Tauwehe

$$\frac{1}{2} = 0.5$$
