idk how to continue from here.

@dpaInc , try this out!

saifoo.khan · Answer

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..

anonymous · Answer

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... :(

lgbasallote · Answer

so it;s still same?

anonymous · Answer

is the 32% decrease only the ones being helped?  if yes, then it wouldn't be the same...
