Question

four friends o,b,z,v went to a trip.o paid 2/7 of the bill and rest of bill was shared byb,,z,v.what fraction of bill was paid by each

Answer 1

o =2/7
remaining = 1 -2/7 =5/7
so each of remaining = 5/7 ×1/3 =5/21

Answer 2

As it is given in the question that "o" paid 2/7 th of the total bill.
That means part of the bill to be paid by the remaining members
=1-[2/7]
=[7-2]/7
=5/7

Now this will be shared equally among three members, so each member will have to pay now
=[1/3[x[5/7]
=5/21

So, the fraction of bill  paid by each = 5/21
