im not sure but i will try it out,
1/21 * 100 = 4.76% were the helpers. ON TOTAL.
And since the total popl decreased, the ratio should remain the same (i think)
Next, thinking..

thing is... is that 32% include the helpers? when u say a decrease total of 32%, i'm assuming the whole population so shouldn't the ratio still be 1:20?
idk... :(

Ratio will remain same even after reduction in total population , assuming reduction is uniform across the population.
