Kua tāruatia ki te papatopenga
2.1m=d
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{2.1m}{2.1}=\frac{d}{2.1}
Whakawehea ngā taha e rua o te whārite ki te 2.1, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.
m=\frac{d}{2.1}
Mā te whakawehe ki te 2.1 ka wetekia te whakareanga ki te 2.1.
m=\frac{10d}{21}
Whakawehe d ki te 2.1 mā te whakarea d ki te tau huripoki o 2.1.
