Kua tāruatia ki te papatopenga
r=15000ab
Whakareatia te 3000 ki te 5, ka 15000.
15000ab=r
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
15000ba=r
He hanga arowhānui tō te whārite.
\frac{15000ba}{15000b}=\frac{r}{15000b}
Whakawehea ngā taha e rua ki te 15000b.
a=\frac{r}{15000b}
Mā te whakawehe ki te 15000b ka wetekia te whakareanga ki te 15000b.
r=15000ab
Whakareatia te 3000 ki te 5, ka 15000.
15000ab=r
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{15000ab}{15000a}=\frac{r}{15000a}
Whakawehea ngā taha e rua ki te 15000a.
b=\frac{r}{15000a}
Mā te whakawehe ki te 15000a ka wetekia te whakareanga ki te 15000a.
