Whakaoti i te 1/5+2/3*9*0,1-sqrt{0,3}*sqrt{0,3}=

$$\frac { 1 } { 5 } + \frac { 2 } { 3 } \cdot 9 \cdot 0,1 - \sqrt { 0,3 } \cdot \sqrt { 0,3 } =$$

Aromātai

$$0.5$$

Ngā Upane Otinga

Whakareatia te \sqrt{0.3} ki te \sqrt{0.3}, ka 0.3.

$$\frac{1}{5}+\frac{2}{3}\times 9\times 0.1-0.3$$

Tuhia te \frac{2}{3}\times 9 hei hautanga kotahi.

$$\frac{1}{5}+\frac{2\times 9}{3}\times 0.1-0.3$$

Whakareatia te 2 ki te 9, ka 18.

$$\frac{1}{5}+\frac{18}{3}\times 0.1-0.3$$

Whakawehea te 18 ki te 3, kia riro ko 6.

$$\frac{1}{5}+6\times 0.1-0.3$$

Whakareatia te 6 ki te 0.1, ka 0.6.

$$\frac{1}{5}+0.6-0.3$$

Me tahuri ki tau ā-ira 0.6 ki te hautau \frac{6}{10}. Whakahekea te hautanga \frac{6}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

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

Tā te mea he rite te tauraro o \frac{1}{5} me \frac{3}{5}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

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

Tāpirihia te 1 ki te 3, 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 tango rāua mā te tango i ō raua taurunga.

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

Tangohia te 3 i te 8, 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.

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

Tauwehe

$$\frac{1}{2} = 0.5$$
