The ratio of helper to learner in OpenStudy is 1:20 during regular time. Over the summer, the total population of OpenStudy decreased by 32%. What will be the ratio of helper to learner in the new population?

    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... :(

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

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