Write the ratio 12:9 as an equivalent ratio of 4:x.(1 point)
$$

1 answer

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.
