Whakaoti i te 1/5-2/1*(3/2-1)+0.3

$$\frac { 1 } { 5 } - \frac { 2 } { 1 } \times ( \frac { 3 } { 2 } - 1 ) + 0.3$$

Aromātai

$$-0.5$$

Ngā Upane Otinga

Ka whakawehea he tau ki te tahi, hua ai ko ia anō.

$$\frac{1}{5}-2\left(\frac{3}{2}-1\right)+0.3$$

Me tahuri te 1 ki te hautau \frac{2}{2}.

$$\frac{1}{5}-2\left(\frac{3}{2}-\frac{2}{2}\right)+0.3$$

Tā te mea he rite te tauraro o \frac{3}{2} me \frac{2}{2}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{1}{5}-2\times \frac{3-2}{2}+0.3$$

Tangohia te 2 i te 3, ka 1.

$$\frac{1}{5}-2\times \frac{1}{2}+0.3$$

Me whakakore te 2 me te 2.

$$\frac{1}{5}-1+0.3$$

Me tahuri te 1 ki te hautau \frac{5}{5}.

$$\frac{1}{5}-\frac{5}{5}+0.3$$

Tā te mea he rite te tauraro o \frac{1}{5} me \frac{5}{5}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{1-5}{5}+0.3$$

Tangohia te 5 i te 1, ka -4.

$$-\frac{4}{5}+0.3$$

Me tahuri ki tau ā-ira 0.3 ki te hautau \frac{3}{10}.

$$-\frac{4}{5}+\frac{3}{10}$$

Ko te maha noa iti rawa atu o 5 me 10 ko 10. Me tahuri -\frac{4}{5} me \frac{3}{10} ki te hautau me te tautūnga 10.

$$-\frac{8}{10}+\frac{3}{10}$$

Tā te mea he rite te tauraro o -\frac{8}{10} me \frac{3}{10}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-8+3}{10}$$

Tāpirihia te -8 ki te 3, ka -5.

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

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

$$-\frac{1}{2}$$
