To convert a fraction into a decimal, divide the top of the fraction (numerator) by the bottom of the fraction (denominator). In this case, the fraction is

\frac{4}{5}

, so divide 4 by 5.
This equals 0.8
Then, to turn the decimal 0.8 into a percentage, simply move the decimal point two places to the right, turning

Considering

\frac{4}{5}

Percentage can be written in 2 ways.
Suppose we hade 60 percent. Then this can be written as
60% which is the same as \frac{60}{100}
So percentage is counting in

\frac{1}{100}

Multiply by 1 in the form of

1 = \frac{2}{2}

and then by

1 = \frac{10}{10}

\frac{4}{5} \times \frac{2}{2} \times \frac{10}{10} \equiv \frac{8}{10} \times \frac{10}{10} \equiv \frac{80}{100}

So,

\frac{4}{5} \Rightarrow 80 % \Rightarrow \frac{80}{100}
