Mr. Someone has 2/3 of a package of ammunition for his hunting trip. When he comes back, he's only used 1/6 of it. How much is left?

2/3  -  U  =  1/6    where U is the fractional part used

 

Rearrange as

 

2/3  - 1/6  = U

 

4/6  -  1/6  =  U

 

3/6   =  U

 

1/2  =  U   ⇒     1/2 of the package used
