A, B ,C, D, and E went to a restaurant. 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 was paid by each?

Given that A, B ,C, D and E went to a restaurant and paid the bill together.

A paid = 1/2
B paid = 1/5

We need to find out the fraction of the bill paid by C,D and E.

Let us consider the fraction paid by C,D and E be = X

As the bill is paid by all together so let consider the whole bill as 1.The bill is taken as whole so the bill is 1

So combining all the above data, the equation becomes

A + B + C + D + E = 1

1/2 + 1/5 + x + x + x = 1
(5 + 2)/10 + 3x = 1
7/10 + 3x = 1

7+30X / 10 = 1

7+30X = 10

30X= 3

x = 3/30
x = 1/10

Therefore the fraction of bill paid by C,D and E is 1 /10
