Whakaoti i te 31/2+15/39+(-35)

$$3 \frac { 1 } { 2 } + \frac { 15 } { 39 } + ( - 35 )$$

Aromātai

$$-\frac{809}{26}\approx -31.115384615$$

Ngā Upane Otinga

Whakareatia te 3 ki te 2, ka 6.

$$\frac{6+1}{2}+\frac{15}{39}-35$$

Tāpirihia te 6 ki te 1, ka 7.

$$\frac{7}{2}+\frac{15}{39}-35$$

Whakahekea te hautanga \frac{15}{39} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$\frac{7}{2}+\frac{5}{13}-35$$

Ko te maha noa iti rawa atu o 2 me 13 ko 26. Me tahuri \frac{7}{2} me \frac{5}{13} ki te hautau me te tautūnga 26.

$$\frac{91}{26}+\frac{10}{26}-35$$

Tā te mea he rite te tauraro o \frac{91}{26} me \frac{10}{26}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{91+10}{26}-35$$

Tāpirihia te 91 ki te 10, ka 101.

$$\frac{101}{26}-35$$

Me tahuri te 35 ki te hautau \frac{910}{26}.

$$\frac{101}{26}-\frac{910}{26}$$

Tā te mea he rite te tauraro o \frac{101}{26} me \frac{910}{26}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{101-910}{26}$$

Tangohia te 910 i te 101, ka -809.

$$-\frac{809}{26}$$

Tauwehe

$$-\frac{809}{26} = -31\frac{3}{26} = -31.115384615384617$$
