Not even one. 2/5 is only 4/5 of a full half. 

To find that answer, divide 2/5 by 1/2 .

(2/5) / (1/2)

2/5 X 2

4/5

Let's look at this again......I'll admit....it is confusing  [ even to me  !!! ]

 

Suppose we wanted to know how many 8s there were in 16.........we would divide 16 by 8  to get 2

 

So.....to find how  many 1/2's there were in  2/5, we would divide 2/5 by 1/2

 

So

 

2/5 /   1/2   =

 

2/5 *  2/1   =

 

4/5

 

Guest's answer makes sense  because

 

4/5 of 1/2   = 4/10   = 2/5

 

 

cool cool cool
