Final answer:

To find the value of x in the proportion 1/2 over 4 = x over 28, we can solve the proportion by cross multiplication. The value of x is 3 1/2.

Step-by-step explanation:

To find the value of x in the proportion 1/2 over 4 = x over 28, we can solve the proportion by cross multiplication.



First, set up the proportion: 1/2 over 4 = x over 28.



Cross multiply to solve for x: (1/2) * 28 = 4 * x.



Simplify: 14 = 4x.



Divide both sides by 4 to solve for x: x = 14/4 = 3 1/2.
