140xx_{40}\times 5=100
Whakareatia te 7 ki te 20, ka 140.
700xx_{40}=100
Whakareatia te 140 ki te 5, ka 700.
700x_{40}x=100
He hanga arowhānui tō te whārite.
\frac{700x_{40}x}{700x_{40}}=\frac{100}{700x_{40}}
Whakawehea ngā taha e rua ki te 700x_{40}.
x=\frac{100}{700x_{40}}
Mā te whakawehe ki te 700x_{40} ka wetekia te whakareanga ki te 700x_{40}.
x=\frac{1}{7x_{40}}
Whakawehe 100 ki te 700x_{40}.
