To find a ratio equivalent to the ratio 7:9, we need to multiply or divide both the numerator and denominator by the same non-zero number. Let's multiply both the numerator and denominator by 2:

7:9 = (7*2) : (9*2) = 14 : 18

Now, let's use this ratio to write a proportion. A proportion is an equation that equates two ratios. In this case, we'll use the ratio 14:18. We can write it as:

14/18 = x/1

In this proportion, the numerator represents one part of a quantity and the denominator represents the corresponding part. To solve for "x," we need to cross-multiply:

14 * 1 = 18 * x

14 = 18x

Now, divide both sides by 18 to isolate "x":

14/18 = x

Simplifying the fraction gives us:

7/9 = x

Therefore, the proportion equivalent to the ratio 7:9 is 7/9 = x/1.
