\frac{5}{9}x=\frac{10}{20}
Pahekotia te x me -\frac{4}{9}x, ka \frac{5}{9}x.
\frac{5}{9}x=\frac{1}{2}
Whakahekea te hautanga \frac{10}{20} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 10.
x=\frac{1}{2}\times \frac{9}{5}
Me whakarea ngā taha e rua ki te \frac{9}{5}, te tau utu o \frac{5}{9}.
x=\frac{1\times 9}{2\times 5}
Me whakarea te \frac{1}{2} ki te \frac{9}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.
x=\frac{9}{10}
Mahia ngā whakarea i roto i te hautanga \frac{1\times 9}{2\times 5}.
