В) 9/12=х/4

To solve the given equation (9/12 = x/4), you can use cross-multiplication.

First, rewrite the equation as:

12x = 4 * 9

Multiply 4 and 9:

12x = 36

Divide both sides of the equation by 12:

12x/12 = 36/12

Simplify:

x = 3

Therefore, the value of x that satisfies the equation is x = 3.
