Kua tāruatia ki te papatopenga
x+\frac{1}{5}x=1.8
Whakahekea te hautanga \frac{20}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 20.
\frac{6}{5}x=1.8
Pahekotia te x me \frac{1}{5}x, ka \frac{6}{5}x.
x=1.8\times \frac{5}{6}
Me whakarea ngā taha e rua ki te \frac{5}{6}, te tau utu o \frac{6}{5}.
x=\frac{9}{5}\times \frac{5}{6}
Me tahuri ki tau ā-ira 1.8 ki te hautau \frac{18}{10}. Whakahekea te hautanga \frac{18}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
x=\frac{9\times 5}{5\times 6}
Me whakarea te \frac{9}{5} ki te \frac{5}{6} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.
x=\frac{9}{6}
Me whakakore tahi te 5 i te taurunga me te tauraro.
x=\frac{3}{2}
Whakahekea te hautanga \frac{9}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.
