1/2 and 10/20

to get 1/2 you have to divide 5/10 by 5:

  5   /   5          1     
-----          =   ----- 
 10  /   5          2

to get 10/20 you have to multiply 5/10 by 2:

  5   *   2          10
-----           =    ----
 10  *   2          20

Hope it helps! =)
1/2, 3/6. As 5 is one half of ten, it would be equivalent to 1/2. Since it is equivalent to one half, 3/6 would also be equivalent, as 3 is one half of 6. I hope this helps!
