Answer 1

   \(\dfrac{121212}{242424}+\dfrac{1313}{2626}+\dfrac{20212021}{40424042}\)

= \(\dfrac{12}{24}+\dfrac{13}{26}+\dfrac{2021}{4042}\)

= \(\dfrac{1}{2}+\dfrac{1}{2}+\dfrac{1}{2}\)

= \(\dfrac{3}{2}\)

Answer 2

121212/242424+1313/2626+20212021/404244024

= 1/2+1/2+1/2 

=3/2

Answer 3

121212/242424 + 1313/2626 + 20212021/40424042

= 1/2 + 1/2 + 1/2

= 3/2
