if qrs/r=s what must be true?

Q must equal 1.

Sorry for the multiple posts everyone. It appeared to not be going through.

q = 1 and r can be any value.

To determine what must be true if qrs/r = s, we can start by isolating the variable 'r' by cross-multiplying.

Multiplying both sides of the equation by 'r', we get:

(qrs/r) * r = s * r

This simplifies to:

qrs = sr

Next, we can divide both sides of the equation by 's' to isolate 'r':

(qrs)/s = sr/s

This simplifies to:

qr = r

Now, we can solve for 'r'. Since 'r' appears on both sides of the equation, we can divide both sides by 'r', assuming 'r' is not equal to zero:

qr/r = r/r

This simplifies to:

q = 1

Thus, if qrs/r = s, then the requirement for this equation to be true is that 'q' must equal 1.
