    To find the value of x in the proportion 0.75 : x :: 5 : 8, we can use the concept of cross-multiplication.

    The proportion can be written as: 0.75/x = 5/8

    To solve for x, we can cross-multiply and then solve the resulting equation:

    0.75 * 8 = x * 5

    => 6 = 5x

    Dividing both sides of the equation by 5, we get:

    6/5 = x

    Therefore, x is equal to 6/5 or 1.2.

    Answer: x is equal to 1.2 in the given proportion.
