Whakaoti i te 1/5+1/9-1/5*9

$$\frac { 1 } { 5 } + \frac { 1 } { 9 } - \frac { 1 } { 5 \times 9 }$$

Aromātai

$$\frac{13}{45}\approx 0.288888889$$

Ngā Upane Otinga

Ko te maha noa iti rawa atu o 5 me 9 ko 45. Me tahuri \frac{1}{5} me \frac{1}{9} ki te hautau me te tautūnga 45.

$$\frac{9}{45}+\frac{5}{45}-\frac{1}{5\times 9}$$

Tā te mea he rite te tauraro o \frac{9}{45} me \frac{5}{45}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{9+5}{45}-\frac{1}{5\times 9}$$

Tāpirihia te 9 ki te 5, ka 14.

$$\frac{14}{45}-\frac{1}{5\times 9}$$

Whakareatia te 5 ki te 9, ka 45.

$$\frac{14}{45}-\frac{1}{45}$$

Tā te mea he rite te tauraro o \frac{14}{45} me \frac{1}{45}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{14-1}{45}$$

Tangohia te 1 i te 14, ka 13.

$$\frac{13}{45}$$

Tauwehe

$$\frac{13}{3 ^ {2} \cdot 5} = 0.28888888888888886$$
