Whakaoti i te (7/4-5/6)*(4+4/11)=

$$( \frac { 7 } { 4 } - \frac { 5 } { 6 } ) \cdot ( 4 + \frac { 4 } { 11 } ) =$$

Aromātai

$$4$$

Ngā Upane Otinga

Ko te maha noa iti rawa atu o 4 me 6 ko 12. Me tahuri \frac{7}{4} me \frac{5}{6} ki te hautau me te tautūnga 12.

$$\left(\frac{21}{12}-\frac{10}{12}\right)\left(4+\frac{4}{11}\right)$$

Tā te mea he rite te tauraro o \frac{21}{12} me \frac{10}{12}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{21-10}{12}\left(4+\frac{4}{11}\right)$$

Tangohia te 10 i te 21, ka 11.

$$\frac{11}{12}\left(4+\frac{4}{11}\right)$$

Me tahuri te 4 ki te hautau \frac{44}{11}.

$$\frac{11}{12}\left(\frac{44}{11}+\frac{4}{11}\right)$$

Tā te mea he rite te tauraro o \frac{44}{11} me \frac{4}{11}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{11}{12}\times \frac{44+4}{11}$$

Tāpirihia te 44 ki te 4, ka 48.

$$\frac{11}{12}\times \frac{48}{11}$$

Me whakarea te \frac{11}{12} ki te \frac{48}{11} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{11\times 48}{12\times 11}$$

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

$$\frac{48}{12}$$

Whakawehea te 48 ki te 12, kia riro ko 4.

$$4$$

Tauwehe

$$2^{2}$$
