Kua tāruatia ki te papatopenga
30x=108-90x
Whakamahia te āhuatanga tohatoha hei whakarea te 1.2-x ki te 90.
30x+90x=108
Me tāpiri te 90x ki ngā taha e rua.
120x=108
Pahekotia te 30x me 90x, ka 120x.
x=\frac{108}{120}
Whakawehea ngā taha e rua ki te 120.
x=\frac{9}{10}
Whakahekea te hautanga \frac{108}{120} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 12.
