Tohaina
Kua tāruatia ki te papatopenga
x=5\times 4
Whakaarohia te whārite tuarua. Me whakarea ngā taha e rua ki te 4, te tau utu o \frac{1}{4}.
x=20
Whakareatia te 5 ki te 4, ka 20.
\frac{1}{2}\phi =\frac{1}{4}\times 20
Whakaarohia te whārite tuatahi. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
\frac{1}{2}\phi =5
Whakareatia te \frac{1}{4} ki te 20, ka 5.
\phi =5\times 2
Me whakarea ngā taha e rua ki te 2, te tau utu o \frac{1}{2}.
\phi =10
Whakareatia te 5 ki te 2, ka 10.
\phi =10 x=20
Kua oti te pūnaha te whakatau.
