Kua tāruatia ki te papatopenga
\frac{18}{5}x=360
Pahekotia te x me \frac{13}{5}x, ka \frac{18}{5}x.
x=360\times \frac{5}{18}
Me whakarea ngā taha e rua ki te \frac{5}{18}, te tau utu o \frac{18}{5}.
x=\frac{360\times 5}{18}
Tuhia te 360\times \frac{5}{18} hei hautanga kotahi.
x=\frac{1800}{18}
Whakareatia te 360 ki te 5, ka 1800.
x=100
Whakawehea te 1800 ki te 18, kia riro ko 100.
