Answer:

\dfrac{1}{3}(b-21)

Step-by-step explanation:

We need to find an equivalent expression for \dfrac{1}{3}b-7

The denominator of first fraction is 3 and that of other is 1.

\dfrac{1}{3}b-7\\\\=\dfrac{b-21}{3}

or

=\dfrac{1}{3}(b-21)

Hence, the equivalent expression is \dfrac{1}{3}(b-21).
