Kua tāruatia ki te papatopenga
x\times \frac{4}{5}=120
Whakahekea te hautanga \frac{80}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 20.
x=120\times \frac{5}{4}
Me whakarea ngā taha e rua ki te \frac{5}{4}, te tau utu o \frac{4}{5}.
x=\frac{120\times 5}{4}
Tuhia te 120\times \frac{5}{4} hei hautanga kotahi.
x=\frac{600}{4}
Whakareatia te 120 ki te 5, ka 600.
x=150
Whakawehea te 600 ki te 4, kia riro ko 150.
