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.
