Rearrange the formula X = mb using m as the quantity of interest

To rearrange the formula \( X = mb \) to solve for \( m \), you can isolate \( m \) on one side of the equation. This can be done by dividing both sides of the equation by \( b \):

\[
m = \frac{X}{b}
\]

So the rearranged formula for \( m \) is:

\[
m = \frac{X}{b}
\]
