Question

Express M in terms of B and n: B = 3Mn 2

Answer 1

We are given the expression B=3Mn/2 and told to express M in terms of B and n. This means that we should apply mathematical operations on both sides of the equation so we "isolate " M on one side of the equality sign. We begin with the given equation

$B=\frac{3\cdot M\cdot n}{2}$

First, we multiply both sides by 2, so we get

$2\cdot B=3\cdot M\cdot n$

Next, we divide by 3 on both sides, so we get

$\frac{2\cdot B}{3}=M\cdot n$

Finally, we divide both sides by n, so we get

$\frac{2\cdot B}{3\cdot n}=M$

In this case, we have succesfully expressed M in terms of B and n
