    can you write out how to solve it? Then I'll help out with the properties used

    you can also do it like this 4(5/20) would turn into (4*5)/20 then 4*5 = 20 so we really have 20/20 = 1

    as for the properties used, there isn't some really fancy name for it. You're just doing simple multiplication and division. I'm not sure what the teacher is trying to get you to do here I guess you could say "associative property" when rearranging terms basically 4(5/20) = 4*5*(1/20) = (4*5)*(1/20) but that seems like we're making things more complicated than they have to be
