Tohaina
Kua tāruatia ki te papatopenga
w\times \frac{3}{20}=6
Whakahekea te hautanga \frac{15}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
w=6\times \frac{20}{3}
Me whakarea ngā taha e rua ki te \frac{20}{3}, te tau utu o \frac{3}{20}.
w=\frac{6\times 20}{3}
Tuhia te 6\times \frac{20}{3} hei hautanga kotahi.
w=\frac{120}{3}
Whakareatia te 6 ki te 20, ka 120.
w=40
Whakawehea te 120 ki te 3, kia riro ko 40.
