Whakaoti i te 59/10--91/2=

$$5 \frac { 9 } { 10 } - - 9 \frac { 1 } { 2 } =$$

Aromātai

$$\frac{77}{5}=15.4$$

Ngā Upane Otinga

Whakareatia te 5 ki te 10, ka 50.

$$\frac{50+9}{10}-\left(-\frac{9\times 2+1}{2}\right)$$

Tāpirihia te 50 ki te 9, ka 59.

$$\frac{59}{10}-\left(-\frac{9\times 2+1}{2}\right)$$

Whakareatia te 9 ki te 2, ka 18.

$$\frac{59}{10}-\left(-\frac{18+1}{2}\right)$$

Tāpirihia te 18 ki te 1, ka 19.

$$\frac{59}{10}-\left(-\frac{19}{2}\right)$$

Ko te tauaro o -\frac{19}{2} ko \frac{19}{2}.

$$\frac{59}{10}+\frac{19}{2}$$

Ko te maha noa iti rawa atu o 10 me 2 ko 10. Me tahuri \frac{59}{10} me \frac{19}{2} ki te hautau me te tautūnga 10.

$$\frac{59}{10}+\frac{95}{10}$$

Tā te mea he rite te tauraro o \frac{59}{10} me \frac{95}{10}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{59+95}{10}$$

Tāpirihia te 59 ki te 95, ka 154.

$$\frac{154}{10}$$

Whakahekea te hautanga \frac{154}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{77}{5}$$

Tauwehe

$$\frac{7 \cdot 11}{5} = 15\frac{2}{5} = 15.4$$
