Tohaina
Kua tāruatia ki te papatopenga
40\times \frac{5}{4}=w
Me whakarea ngā taha e rua ki te \frac{5}{4}, te tau utu o \frac{4}{5}.
\frac{40\times 5}{4}=w
Tuhia te 40\times \frac{5}{4} hei hautanga kotahi.
\frac{200}{4}=w
Whakareatia te 40 ki te 5, ka 200.
50=w
Whakawehea te 200 ki te 4, kia riro ko 50.
w=50
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
