Kua tāruatia ki te papatopenga
\frac{6}{5}x-x=0.8
Whakahekea te hautanga \frac{120}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 20.
\frac{1}{5}x=0.8
Pahekotia te \frac{6}{5}x me -x, ka \frac{1}{5}x.
x=0.8\times 5
Me whakarea ngā taha e rua ki te 5, te tau utu o \frac{1}{5}.
x=4
Whakareatia te 0.8 ki te 5, ka 4.
