thank you @Steve :)

so its 37.5?

To solve the equation 1/2.5 = 15/x, you can cross-multiply and then solve for x.

Here are the steps:

Step 1: Cross-multiply
Multiply the numerator of the left fraction by the denominator of the right fraction and vice versa. In this case, it looks like this: (1 * x) = (2.5 * 15).

Step 2: Simplify
Perform the multiplication on both sides of the equation: x = 37.5.

Therefore, x equals 37.5.
