Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawehea ngā taha e rua ki te 25.

$$x+\frac{40}{100}=\frac{11}{25}$$

Whakahekea te hautanga \frac{40}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 20.

$$x+\frac{2}{5}=\frac{11}{25}$$

Tangohia te \frac{2}{5} mai i ngā taha e rua.

$$x=\frac{11}{25}-\frac{2}{5}$$

Ko te maha noa iti rawa atu o 25 me 5 ko 25. Me tahuri \frac{11}{25} me \frac{2}{5} ki te hautau me te tautūnga 25.

$$x=\frac{11}{25}-\frac{10}{25}$$

Tā te mea he rite te tauraro o \frac{11}{25} me \frac{10}{25}, me tango rāua mā te tango i ō raua taurunga.

$$x=\frac{11-10}{25}$$

Tangohia te 10 i te 11, ka 1.

$$x=\frac{1}{25}$$
