$$1- \frac{ 8 }{ 55 } - \frac{ 4 }{ 11 } \div 3$$

Aromātai

$$\frac{11}{15}\approx 0.733333333$$

Ngā Upane Otinga

Me tahuri te 1 ki te hautau \frac{55}{55}.

$$\frac{55}{55}-\frac{8}{55}-\frac{\frac{4}{11}}{3}$$

Tā te mea he rite te tauraro o \frac{55}{55} me \frac{8}{55}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{55-8}{55}-\frac{\frac{4}{11}}{3}$$

Tangohia te 8 i te 55, ka 47.

$$\frac{47}{55}-\frac{\frac{4}{11}}{3}$$

Tuhia te \frac{\frac{4}{11}}{3} hei hautanga kotahi.

$$\frac{47}{55}-\frac{4}{11\times 3}$$

Whakareatia te 11 ki te 3, ka 33.

$$\frac{47}{55}-\frac{4}{33}$$

Ko te maha noa iti rawa atu o 55 me 33 ko 165. Me tahuri \frac{47}{55} me \frac{4}{33} ki te hautau me te tautūnga 165.

$$\frac{141}{165}-\frac{20}{165}$$

Tā te mea he rite te tauraro o \frac{141}{165} me \frac{20}{165}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{141-20}{165}$$

Tangohia te 20 i te 141, ka 121.

$$\frac{121}{165}$$

Whakahekea te hautanga \frac{121}{165} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 11.

$$\frac{11}{15}$$

Tauwehe

$$\frac{11}{3 \cdot 5} = 0.7333333333333333$$
