Whakaoti i te 41/10-93/5=

$$4 \frac { 1 } { 10 } - 9 \frac { 3 } { 5 } =$$

Aromātai

$$-\frac{11}{2}=-5.5$$

Ngā Upane Otinga

Whakareatia te 4 ki te 10, ka 40.

$$\frac{40+1}{10}-\frac{9\times 5+3}{5}$$

Tāpirihia te 40 ki te 1, ka 41.

$$\frac{41}{10}-\frac{9\times 5+3}{5}$$

Whakareatia te 9 ki te 5, ka 45.

$$\frac{41}{10}-\frac{45+3}{5}$$

Tāpirihia te 45 ki te 3, ka 48.

$$\frac{41}{10}-\frac{48}{5}$$

Ko te maha noa iti rawa atu o 10 me 5 ko 10. Me tahuri \frac{41}{10} me \frac{48}{5} ki te hautau me te tautūnga 10.

$$\frac{41}{10}-\frac{96}{10}$$

Tā te mea he rite te tauraro o \frac{41}{10} me \frac{96}{10}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{41-96}{10}$$

Tangohia te 96 i te 41, ka -55.

$$\frac{-55}{10}$$

Whakahekea te hautanga \frac{-55}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$-\frac{11}{2}$$

Tauwehe

$$-\frac{11}{2} = -5\frac{1}{2} = -5.5$$
