For this case what we must do is a division using the following relationship: [tex]N = (total amount) / (partial amount)
[/tex]Substituting values we have: [tex]N = (4) / (2/5)
[/tex] Rewriting the fraction we have: [tex]N = (20) / (2)
[/tex] Simplifying we have: [tex]N = 10
[/tex] Answer: The number of times repeated 2/5 for 4 is: 10
