<h3>Answer: D) 12.5%</h3>

=================================

Work Shown:

A = old amount = 48

B = new amount = 54

C = percent change

C = [(B-A)/A]*100%

C = [(54-48)/48]*100%

C = [6/48]*100%

C = 0.125*100%

C = 12.5%

The value of C is positive to indicate a percent increase.

So we have a 12.5% increase.

-----------

Note how 12.5% of 48 is 0.125*48 = 6

A 12.5% increase of 48 means we have an increase of 6

So, 48+6 = 54, which matches with what the instructions say. This confirms the answer.

As a shortcut, we could check it by saying 1.125*48 = 54

Sindrei [870]

Step-by-step explanation:

We need to find an expression for \dfrac{\dfrac{-5}{6}}{\dfrac{-1}{3}}.

We can solve it as follows.

We know that,

\dfrac{\dfrac{a}{b}}{\dfrac{c}{d}}=\dfrac{a}{b}\times \dfrac{d}{c}

So,

\dfrac{\dfrac{-5}{6}}{\dfrac{-1}{3}}=\dfrac{-5}{6}\times -3\\\\=\dfrac{5}{2}

or

=2\dfrac{1}{2}

Hence, this is the required solution.
