Two masses $M$ and $M/2$ are joint together by means of a light inextensible string passes over a frictionless pulley as shown in figure. When bigger mass is released the small one will ascend with an acceleration of
$a = \left( {\frac{{{m_2} - {m_1}}}{{{m_1} + {m_2}}}} \right)\;g = \left( {\frac{{m - m/2}}{{m + m/2}}} \right)\;g = \frac{g}{3}$
