Oct 13, 2025 by wbrum.org 119 views

Understanding the Formula

The given formula is $$K = L M N$$, where K, L, M, and N are variables. To solve for M, we need to isolate M on one side of the equation. This involves rearranging the formula to make M the subject.

Rearranging the Formula

To solve for M, we can start by dividing both sides of the equation by LN. This will cancel out the LN term on the right-hand side, leaving us with M on its own.

Deriving the Formula for M

By dividing both sides of the equation by LN, we get:

\frac{K}{L N} = M

This can be rewritten as:

M = \frac{K}{L N}

Comparing with the Options

Now that we have derived the formula for M, let's compare it with the options provided:

A) $$M = K L / N$$ B) $$M = L N / K$$ C) $$M = K / L N$$ D) $$M = L N K$$

Conclusion

Based on our derivation, the correct formula for M is:

M = \frac{K}{L N}

This matches option C) $$M = K / L N$$.

Why is this Formula Correct?

This formula is correct because we have isolated M on one side of the equation by dividing both sides by LN. This is a valid algebraic manipulation that allows us to solve for M in terms of K, L, and N.

What if the Formula was Different?

If the formula was different, such as $$K = L + M + N$$, then we would need to use a different approach to solve for M. In this case, we would need to use algebraic manipulations such as subtraction and rearrangement to isolate M.
