2,4:x= 6:4,5

To solve this equation, we need to find the value of x. We can set up a proportion using the given ratios:

2/4 = 6/4.5

To simplify this equation, we multiply both sides by 4.5 to eliminate the denominators:

2 * 4.5 = 6 * 4

9 = 24

Since 9 does not equal 24, this equation does not have a valid solution.
