Answer 2

Keep in mind that \(\% = \dfrac{1}{100}\)

Therefore, to convert something like \(\dfrac{4}{5}\) to an appropriate equivalent fraction, perform the following steps:

Create the following proportion.

\(\dfrac{4}{5} = \dfrac{x}{100}\)

Then solve for \(x\)

In this case, \(x\) = 20, therefore,

\(\dfrac{4}{5} = \dfrac{20}{100}\)

Next write \(\frac{20}{100}\) as:

\(20\left(\dfrac{1}{100}\right)\)

Now remember we said that \(\dfrac{1}{100} = \%\) so

\(\dfrac{4}{5} = 20\%\)
