Kua tāruatia ki te papatopenga
x=4\times \frac{5}{8}
Me whakarea ngā taha e rua ki te \frac{5}{8}.
x=\frac{4\times 5}{8}
Tuhia te 4\times \frac{5}{8} hei hautanga kotahi.
x=\frac{20}{8}
Whakareatia te 4 ki te 5, ka 20.
x=\frac{5}{2}
Whakahekea te hautanga \frac{20}{8} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.
