Respuesta :

 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
