Rizwan gave 2/7 of the fruit trifle to his friend
That means there was +7%2F7+-+2%2F7+=+5%2F7+
of the fruit trifle left
-------------------------------------
(a)
Rizwan ate +%281%2F5%29%2A%285%2F7%29+=+1%2F7+ of what
he started with
--------------------------------
(b)
So far, +2%2F7+%2B+1%2F7+=+3%2F7+ is gone.
There is +7%2F7+-+3%2F7+=+4%2F7+ of
the fruit trifle remaining
