A, B, C, D, and E went to a restaurant for dinner.  A paid 1/2 of the bill, B paid 1/5 of the bill and rest of the bill was shared equally by C, D, and E.  What fraction of the bill was paid by each?

A = 5/10

B = 2/10

C = 1/10

D = 1/10

E = 1/10

A paid  1/2  of the bill and paid  1/5  of the bill.

 

Together, they paid  1/2 + 1/5  =  5/10 + 2/10  =  7/10  of the bill.

 

The remaining portion  1 - 7/10  =  3/10  was equally shared by C, D, and E.

 

One-third of  3/10  is  1/10.

 

So each of  C, D, and E  paid  1/10  of the bill.
