Thank you!!

4/s = -2/9

Cross multiply.

-2s = 36

s = -18

To solve the equation 4/s = -2/9, you need to isolate the variable s on one side of the equation. Here's how you can do it:

Step 1: Cross-multiply the fractions by multiplying the numerator of the first fraction with the denominator of the second fraction, and vice versa.

4/s = -2/9 --> 4 * 9 = -2 * s

Step 2: Simplify both sides of the equation.

36 = -2s

Step 3: Divide both sides of the equation by -2 to solve for s.

36 / -2 = -2s / -2

-18 = s

Thus, the solution to the equation 4/s = -2/9 is s = -18.
