To determine which ratio is equivalent to the fraction 7/3 and would result in a valid proportion, we need to find a ratio that is equal to the fraction 7/3.
We can set up the proportion as follows:
7/3 = x/y
To find the valid ratio, we need to find the values of x and y that satisfy this equation. One possible valid ratio would be:
x = 14
y = 6
Substituting these values into the equation, we get:
7/3 = 14/6
This is a valid proportion since both sides of the equation are equal.
Therefore, a valid ratio that is equivalent to 7/3 is 14:6.
