Answer:
4
Explanation:
Here are two ways to think about it:
10 fruits -- clustered into 5 groups of 2 (each group represents one fifth) ...
1 2 3 4 5 6 7 8 9 10
[ _ _ ] [ _ _ ] [ _ _ ] [ _ _ ] [ _ _ ]
1 1 1 1 1
---- ---- ---- ------ -----
5 5 5 5 5
As you can see, two of those five fifths represent 4 apples.
-------------------------------------------------------------------------------------------------------
Or you can set up the problem like this and solve for x.
2 x
---- = ----
5 10
5x = 20
x = 4
