Answer 1

a. 3/2*4/3*5/4*.....*2011/2010*2012/2011
se simplifica aproape toate nr: 3,4,5.........2011 
ramane 2012/2=1006

b. 1/2*2/3*3/4*....*2009/2010*2010/2011
se simplifica 2,3,4,......2010
ramane 1/2011

Answer 2

a. $\frac{3}{2} * \frac{4}{3} * \frac{5}{4} *...* \frac{2011}{2010}* \frac{2012}{2011}$
simplifici nr: 3,4,5......2011 
ramane $\frac{2012}{2}=1006$

b. $\frac{1}{2}* \frac{2}{3} \frac{3}{4} *...* \frac{2009}{2010} * \frac{2010}{2011}$
simplifici nr: 2,3,4.....2010
ramane $\frac{1}{2011}$
