Kua tāruatia ki te papatopenga
20=5\times 20cm
Me whakarea ngā taha e rua o te whārite ki te 100, arā, te tauraro pātahi he tino iti rawa te kitea o 100,20.
20=100cm
Whakareatia te 5 ki te 20, ka 100.
100cm=20
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
100mc=20
He hanga arowhānui tō te whārite.
\frac{100mc}{100m}=\frac{20}{100m}
Whakawehea ngā taha e rua ki te 100m.
c=\frac{20}{100m}
Mā te whakawehe ki te 100m ka wetekia te whakareanga ki te 100m.
c=\frac{1}{5m}
Whakawehe 20 ki te 100m.
20=5\times 20cm
Me whakarea ngā taha e rua o te whārite ki te 100, arā, te tauraro pātahi he tino iti rawa te kitea o 100,20.
20=100cm
Whakareatia te 5 ki te 20, ka 100.
100cm=20
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{100cm}{100c}=\frac{20}{100c}
Whakawehea ngā taha e rua ki te 100c.
m=\frac{20}{100c}
Mā te whakawehe ki te 100c ka wetekia te whakareanga ki te 100c.
m=\frac{1}{5c}
Whakawehe 20 ki te 100c.
