Question

How many 2/5 are in 4?

Answer 1

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