Whakaoti i te x+1/5x=4/5

$$x + \frac { 1 } { 5 } x = \frac { 4 } { 5 }$$

Whakaoti mō x

$$x=\frac{2}{3}\approx 0.666666667$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$\frac{6}{5}x=\frac{4}{5}$$

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

$$x=\frac{4}{5}\times \frac{5}{6}$$

Me whakarea te \frac{4}{5} ki te \frac{5}{6} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$x=\frac{4\times 5}{5\times 6}$$

Me whakakore tahi te 5 i te taurunga me te tauraro.

$$x=\frac{4}{6}$$

Whakahekea te hautanga \frac{4}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$x=\frac{2}{3}$$
