To find the equivalent ratio, we need to find the value of x that makes the two ratios equivalent.
We can do this by setting up a proportion using the given ratio:
12/9 = 4/x
To solve for x, cross multiply and solve for x:
12x = 4*9
12x = 36
Divide both sides by 12 to isolate x:
x = 36/12
x = 3
Therefore, the equivalent ratio of 12:9 as 4:x is 4:3.
