Whakaoti i te 10-6*3/5/15*frac{4{5}}+12/5

$$\frac { 10 - 6 \times \frac { 3 } { 5 } } { 15 \times \frac { 4 } { 5 } } + \frac { 12 } { 5 }$$

Aromātai

$$\frac{44}{15}\approx 2.933333333$$

Ngā Upane Otinga

Tuhia te 6\times \frac{3}{5} hei hautanga kotahi.

$$\frac{10-\frac{6\times 3}{5}}{15\times \frac{4}{5}}+\frac{12}{5}$$

Whakareatia te 6 ki te 3, ka 18.

$$\frac{10-\frac{18}{5}}{15\times \frac{4}{5}}+\frac{12}{5}$$

Me tahuri te 10 ki te hautau \frac{50}{5}.

$$\frac{\frac{50}{5}-\frac{18}{5}}{15\times \frac{4}{5}}+\frac{12}{5}$$

Tā te mea he rite te tauraro o \frac{50}{5} me \frac{18}{5}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{\frac{50-18}{5}}{15\times \frac{4}{5}}+\frac{12}{5}$$

Tangohia te 18 i te 50, ka 32.

$$\frac{\frac{32}{5}}{15\times \frac{4}{5}}+\frac{12}{5}$$

Tuhia te 15\times \frac{4}{5} hei hautanga kotahi.

$$\frac{\frac{32}{5}}{\frac{15\times 4}{5}}+\frac{12}{5}$$

Whakareatia te 15 ki te 4, ka 60.

$$\frac{\frac{32}{5}}{\frac{60}{5}}+\frac{12}{5}$$

Whakawehea te 60 ki te 5, kia riro ko 12.

$$\frac{\frac{32}{5}}{12}+\frac{12}{5}$$

Tuhia te \frac{\frac{32}{5}}{12} hei hautanga kotahi.

$$\frac{32}{5\times 12}+\frac{12}{5}$$

Whakareatia te 5 ki te 12, ka 60.

$$\frac{32}{60}+\frac{12}{5}$$

Whakahekea te hautanga \frac{32}{60} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$\frac{8}{15}+\frac{12}{5}$$

Ko te maha noa iti rawa atu o 15 me 5 ko 15. Me tahuri \frac{8}{15} me \frac{12}{5} ki te hautau me te tautūnga 15.

$$\frac{8}{15}+\frac{36}{15}$$

Tā te mea he rite te tauraro o \frac{8}{15} me \frac{36}{15}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{8+36}{15}$$

Tāpirihia te 8 ki te 36, ka 44.

$$\frac{44}{15}$$

Tauwehe

$$\frac{2 ^ {2} \cdot 11}{3 \cdot 5} = 2\frac{14}{15} = 2.933333333333333$$
