Tohaina
Kua tāruatia ki te papatopenga
\frac{3n}{10}P=60
He hanga arowhānui tō te whārite.
\frac{10\times \frac{3n}{10}P}{3n}=\frac{10\times 60}{3n}
Whakawehea ngā taha e rua ki te 0.3n.
P=\frac{10\times 60}{3n}
Mā te whakawehe ki te 0.3n ka wetekia te whakareanga ki te 0.3n.
P=\frac{200}{n}
Whakawehe 60 ki te 0.3n.
\frac{3P}{10}n=60
He hanga arowhānui tō te whārite.
\frac{10\times \frac{3P}{10}n}{3P}=\frac{10\times 60}{3P}
Whakawehea ngā taha e rua ki te 0.3P.
n=\frac{10\times 60}{3P}
Mā te whakawehe ki te 0.3P ka wetekia te whakareanga ki te 0.3P.
n=\frac{200}{P}
Whakawehe 60 ki te 0.3P.
