Whakaoti i te x+20%x=80

$$x+20 \% x=80$$

Whakaoti mō x

$$x = \frac{200}{3} = 66\frac{2}{3} \approx 66.666666667$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$x+\frac{1}{5}x=80$$

Pahekotia te x me \frac{1}{5}x, ka \frac{6}{5}x.

$$\frac{6}{5}x=80$$

Me whakarea ngā taha e rua ki te \frac{5}{6}, te tau utu o \frac{6}{5}.

$$x=80\times \frac{5}{6}$$

Tuhia te 80\times \frac{5}{6} hei hautanga kotahi.

$$x=\frac{80\times 5}{6}$$

Whakareatia te 80 ki te 5, ka 400.

$$x=\frac{400}{6}$$

Whakahekea te hautanga \frac{400}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$x=\frac{200}{3}$$
