1. The equivalent expressions are options C and D

   What are algebraic expressions?

   Algebraic expressions are defined as mathematical expressions comprised of variables and constants.

   Algebraic expressions are made up of operations such as multiplication, division, subtraction, addition, brackets, etc.

   From the information given, we can deduce;

   k/2

   An equivalent expression is equal to the expression and can be written in other forms.

   We can see that C and D are equivalent to k/2

   C = k(1/2) = k/2

   D = k(2k÷2k) /2 = k ( 2k × 1/2k) /2 = k × 1 /2 = k/2

   Hence, the equivalent expressions are options C and D
