\frac{y}{12\left(y+3\right)}-\frac{3}{6\left(y+3\right)}
Ffactora 12y+36. Ffactora 6y+18.
\frac{y}{12\left(y+3\right)}-\frac{3\times 2}{12\left(y+3\right)}
I ychwanegu neu dynnu mynegiannau, rhaid i chi eu ehangu i wneud eu enwaduron yr un fath. Lluosrif lleiaf cyffredin 12\left(y+3\right) a 6\left(y+3\right) yw 12\left(y+3\right). Lluoswch \frac{3}{6\left(y+3\right)} â \frac{2}{2}.
\frac{y-3\times 2}{12\left(y+3\right)}
Gan fod gan \frac{y}{12\left(y+3\right)} a \frac{3\times 2}{12\left(y+3\right)} yr un dynodydd, tynnwch nhw drwy dynnu eu rhifiaduron.
\frac{y-6}{12\left(y+3\right)}
Gwnewch y gwaith lluosi yn y-3\times 2.
\frac{y-6}{12y+36}
Ehangu 12\left(y+3\right).
