I want to reduce the two following fractions:
$$ \frac{2x + 2y}{x + y} $$
$$ \frac{3ab^2}{12ab} $$
I fully understand the concept of reduce fractions of this type:
$$ \frac{15}{20} $$
but i do not know what steps to take for reducing fractions like the two above. Anyone that can explain the steps needed, or point me to a website explaining it?
