Ngā Upane Otinga

Whakareatia te 4 ki te 1, ka 4.

$$4+\frac{1}{2}\times 3-\frac{4.7}{1}+\frac{12}{100}\times 3$$

Whakareatia te \frac{1}{2} ki te 3, ka \frac{3}{2}.

$$4+\frac{3}{2}-\frac{4.7}{1}+\frac{12}{100}\times 3$$

Me tahuri te 4 ki te hautau \frac{8}{2}.

$$\frac{8}{2}+\frac{3}{2}-\frac{4.7}{1}+\frac{12}{100}\times 3$$

Tā te mea he rite te tauraro o \frac{8}{2} me \frac{3}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{8+3}{2}-\frac{4.7}{1}+\frac{12}{100}\times 3$$

Tāpirihia te 8 ki te 3, ka 11.

$$\frac{11}{2}-\frac{4.7}{1}+\frac{12}{100}\times 3$$

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

$$\frac{11}{2}-4.7+\frac{12}{100}\times 3$$

Me tahuri ki tau ā-ira 4.7 ki te hautau \frac{47}{10}.

$$\frac{11}{2}-\frac{47}{10}+\frac{12}{100}\times 3$$

Ko te maha noa iti rawa atu o 2 me 10 ko 10. Me tahuri \frac{11}{2} me \frac{47}{10} ki te hautau me te tautūnga 10.

$$\frac{55}{10}-\frac{47}{10}+\frac{12}{100}\times 3$$

Tā te mea he rite te tauraro o \frac{55}{10} me \frac{47}{10}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{55-47}{10}+\frac{12}{100}\times 3$$

Tangohia te 47 i te 55, ka 8.

$$\frac{8}{10}+\frac{12}{100}\times 3$$

Whakahekea te hautanga \frac{8}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{4}{5}+\frac{12}{100}\times 3$$

Whakahekea te hautanga \frac{12}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$\frac{4}{5}+\frac{3}{25}\times 3$$

Tuhia te \frac{3}{25}\times 3 hei hautanga kotahi.

$$\frac{4}{5}+\frac{3\times 3}{25}$$

Whakareatia te 3 ki te 3, ka 9.

$$\frac{4}{5}+\frac{9}{25}$$

Ko te maha noa iti rawa atu o 5 me 25 ko 25. Me tahuri \frac{4}{5} me \frac{9}{25} ki te hautau me te tautūnga 25.

$$\frac{20}{25}+\frac{9}{25}$$

Tā te mea he rite te tauraro o \frac{20}{25} me \frac{9}{25}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{20+9}{25}$$

Tāpirihia te 20 ki te 9, ka 29.

$$\frac{29}{25}$$

Tauwehe

$$\frac{29}{5 ^ {2}} = 1\frac{4}{25} = 1.16$$
