question related to floor function

Правка en1, от fresher96, 2015-11-06 19:20:33

does this equation hold for all positive integers

floor( z / (x*y) ) = floor( floor(z / x) / y )

if so, how to prove it?

i have already tested it on randomly generated numbers. also, i have previously used it in a problem and it worked fine
