Roinn
Cóipeáladh go dtí an ghearrthaisce
5w\times 2m=3n^{2}\times 4t^{2}
Iolraigh an dá thaobh den chothromóid faoi 15wn^{2}, an comhiolraí is lú de 3n^{2},5w.
10wm=3n^{2}\times 4t^{2}
Méadaigh 5 agus 2 chun 10 a fháil.
10wm=12n^{2}t^{2}
Méadaigh 3 agus 4 chun 12 a fháil.
\frac{10wm}{10w}=\frac{12n^{2}t^{2}}{10w}
Roinn an dá thaobh faoi 10w.
m=\frac{12n^{2}t^{2}}{10w}
Má roinntear é faoi 10w cuirtear an iolrúchán faoi 10w ar ceal.
m=\frac{6n^{2}t^{2}}{5w}
Roinn 12n^{2}t^{2} faoi 10w.
