Kua tāruatia ki te papatopenga
\frac{5}{2}x=20
Me tāpiri te 20 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=20\times \frac{2}{5}
Me whakarea ngā taha e rua ki te \frac{2}{5}, te tau utu o \frac{5}{2}.
x=\frac{20\times 2}{5}
Tuhia te 20\times \frac{2}{5} hei hautanga kotahi.
x=\frac{40}{5}
Whakareatia te 20 ki te 2, ka 40.
x=8
Whakawehea te 40 ki te 5, kia riro ko 8.
