Whakaoti i te (2/3*1/2+1/4):1/3=

$$( \frac { 2 } { 3 } \cdot \frac { 1 } { 2 } + \frac { 1 } { 4 } ) : \frac { 1 } { 3 } =$$

Aromātai

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

Ngā Upane Otinga

Me whakarea te \frac{2}{3} ki te \frac{1}{2} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

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

Me whakakore tahi te 2 i te taurunga me te tauraro.

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

Ko te maha noa iti rawa atu o 3 me 4 ko 12. Me tahuri \frac{1}{3} me \frac{1}{4} ki te hautau me te tautūnga 12.

$$\frac{\frac{4}{12}+\frac{3}{12}}{\frac{1}{3}}$$

Tā te mea he rite te tauraro o \frac{4}{12} me \frac{3}{12}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{\frac{4+3}{12}}{\frac{1}{3}}$$

Tāpirihia te 4 ki te 3, ka 7.

$$\frac{\frac{7}{12}}{\frac{1}{3}}$$

Whakawehe \frac{7}{12} ki te \frac{1}{3} mā te whakarea \frac{7}{12} ki te tau huripoki o \frac{1}{3}.

$$\frac{7}{12}\times 3$$

Tuhia te \frac{7}{12}\times 3 hei hautanga kotahi.

$$\frac{7\times 3}{12}$$

Whakareatia te 7 ki te 3, ka 21.

$$\frac{21}{12}$$

Whakahekea te hautanga \frac{21}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

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

Tauwehe

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