To solve for the value of x in the given proportion, cross multiply the numerator of the first ratio to the denominator of the second and also the denominator of the first to the numerator of the second.
                         (3)(16) = (12)(x)
The value of x is equal to 4. 

Answer:

value of x is 4

Step-by-step explanation:

Ratio defined as the two comparison sizes or number are equial.

i.,e a to b = a:b = [tex]\frac{a}{b}[/tex]

Solve:

3 : 12 = x : 16

By definition of ratio:

[tex]\frac{3}{12} =\frac{x}{16}[/tex]

By cross multiply we get;

[tex]48 = 12x[/tex]

Divide both sides by 12 we get;

4 = x

or

x = 4

Therefore, the value of x is 4
