Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawehea ngā taha e rua ki te 338615.

$$\frac{100-x}{100}=\frac{297237}{338615}$$

Me whakarea ngā taha e rua ki te 100.

$$100-x=\frac{297237}{338615}\times 100$$

Tuhia te \frac{297237}{338615}\times 100 hei hautanga kotahi.

$$100-x=\frac{297237\times 100}{338615}$$

Whakareatia te 297237 ki te 100, ka 29723700.

$$100-x=\frac{29723700}{338615}$$

Whakahekea te hautanga \frac{29723700}{338615} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$100-x=\frac{5944740}{67723}$$

Tangohia te 100 mai i ngā taha e rua.

$$-x=\frac{5944740}{67723}-100$$

Me tahuri te 100 ki te hautau \frac{6772300}{67723}.

$$-x=\frac{5944740}{67723}-\frac{6772300}{67723}$$

Tā te mea he rite te tauraro o \frac{5944740}{67723} me \frac{6772300}{67723}, me tango rāua mā te tango i ō raua taurunga.

$$-x=\frac{5944740-6772300}{67723}$$

Tangohia te 6772300 i te 5944740, ka -827560.

$$-x=-\frac{827560}{67723}$$

Me whakarea ngā taha e rua ki te -1.

$$x=\frac{827560}{67723}$$
