    let's say that the amount of territories of the uk is x then the amount of territories of norway is 0.2x we know that denmark has 2, and that there are 20 total. so the uk and norway combined is 18. so x + 0.2x = 1.2x = 18 x = 18/1.2 = 15 so the uk has 15 territories and norway had 0.2 * 15 = 3 territorries last check: 15 (uk) + 3 (norway) + 2 (denmark) = 20, as it should be.
