Kua tāruatia ki te papatopenga
\frac{x}{\frac{4}{3}}=60
Tāpirihia te 20 ki te 40, ka 60.
x=60\times \frac{4}{3}
Me whakarea ngā taha e rua ki te \frac{4}{3}.
x=\frac{60\times 4}{3}
Tuhia te 60\times \frac{4}{3} hei hautanga kotahi.
x=\frac{240}{3}
Whakareatia te 60 ki te 4, ka 240.
x=80
Whakawehea te 240 ki te 3, kia riro ko 80.
