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.
