Write the ratio 12:9 as an equivalent ratio of 4:x

Answer 1

To find an equivalent ratio for 12:9 in the form 4:x, we need to find the value of x.

We can set up a proportion to determine the value of x:

12/9 = 4/x

To solve for x, we can cross-multiply:

12x = 4(9)

12x = 36

Now, divide both sides of the equation by 12 to solve for x:

x = 36/12

x = 3

Therefore, the equivalent ratio of 12:9 in the form 4:x is 4:3.
