To determine the value of x that makes the ratios equivalent, we need to set up a proportion and solve for x.
The given pair of ratios is x:4 and 45:20.
A proportion can be set up by equating the fractions formed by the ratios:
(x/4) = (45/20)
To solve for x, we can cross-multiply:
20x = 45 * 4
20x = 180
Next, divide both sides of the equation by 20 to isolate x:
x = 180/20
x = 9
So, the value of x that makes the ratios equivalent is 9.
Therefore, the correct answer is B. 9.
Cross multiply and solve for x.

Cross multiply.
4 * 45 = 20x
Can you take it from there?
