Question:

If b does not equal zero, and \(ab = \frac{\mathrm{b} }{\mathrm{4} }\) , what is the value of a?

A \(\frac{\mathrm{1} }{\mathrm{4} }\)
explanation

To solve for a, divide both sides of the equation by b:
\(ab = \frac{\mathrm{b} }{\mathrm{4} }\)
\(ab = \frac{\mathrm{b/4} }{\mathrm{b} }\)
\(a = \frac{\mathrm{b} }{\mathrm{4} } \times \frac{\mathrm{1} }{\mathrm{b}} = \frac{\mathrm{1} }{\mathrm{4} } \)
