Let number of biscuits baked = x.

(3/7) x are in container a.

The remainder = (4/7) x, because (3/7) x + (4/7) x = (7/7) x = x.

Now, (5/8) * (4/7) x = (5/14) x are in container b.

The rest = (3/8) * (4/7) x, because (5/8) * (4/7) x + (3/8) * (4/7) x = (8/8) * (4/7) x = (4/7) x.

So, (3/8) * (4/7) x = (3/14) x are in container c.
