To find the equivalent ratio, we can set up a proportion. We know that 12:9 is equal to 4:x.
This can be written as:
12/9 = 4/x
To solve for x, we can cross multiply:
12x = 9*4
12x = 36
Now, we can solve for x by dividing both sides of the equation by 12:
x = 36/12
x = 3
Therefore, the equivalent ratio of 12:9 as 4:x is 4:3.
