[tex]\frac{1}{5}+\frac{1}{5}+\frac{1}{5}+\frac{1}{5}[/tex]
Step-by-step explanation:
we know that
A unit fraction is a fraction with a numerator equal to [tex]1[/tex]
so
In this problem we have
[tex]\frac{4}{5}[/tex]
rewrite as a sum of unit fractions
[tex]\frac{4}{5}=4*\frac{1}{5}=\frac{1}{5}+\frac{1}{5}+\frac{1}{5}+\frac{1}{5}[/tex]
