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
