To find the value of x in the proportion 0.75 : x :: 5 : 8, we can use the concept of crossmultiplication.
The proportion can be written as: 0.75/x = 5/8
To solve for x, we can crossmultiply 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.
