# If y varies inversely as x and y=3 when x=5 how do you find y when x=2.5?

To find y when x=2.5, we can use the inverse variation formula: y = k/x.

First, we need to find the constant of variation (k). We can do this by substituting the given values of y and x into the formula: 3 = k/5.

Solving for k, we get k = 15.

Now, we can use the value of k to find y when x=2.5: y = 15/2.5.

Simplifying, we find that y = 6.
