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.
