Recall that a factor of an expression is a number or algebraic expression that divides the given expression evenly.
Notice that:
[tex]\begin{gathered} \frac{\frac{2}{5}ab}{\frac{2}{5}}=ab, \\ \frac{\frac{2}{5}ab}{a}=\frac{2}{5}b, \\ \frac{\frac{2}{5}ab}{b}=\frac{2}{5}a. \end{gathered}[/tex]
Therefore:
[tex]\frac{2}{5},a,\text{ and b}[/tex]
are factors of the given expression.
Answer:
[tex]\frac{2}{5},a,b.[/tex]
