Answer:

The American population was 20% of the British population.

Step-by-step explanation:

Let us call $A$ the american population, $B$ the British population before the migration, and $x$ the population that migrated from America to Britannia.

Now, the population $x$ that migrated was 20% of the american population:

$(1).\: \: x = 0.2A$ ,

and the same population $x$ increase the British population by 4%:

$x+B = 1.04B \\\\ (2). \:\:x = 0.04B.$

Combining equation (1) and (2) we get:

$0.2A = 0.04B$

$A = \dfrac{0.04B}{0.2}$

$\boxed{A = 0.2B}$

Thus, the American population was 20% of the British population.
