76/304=81/k what is K and show work plez
siniylev [52]
You can cross multiply and then get k alone so it would look like this:
76         81    
-----  =   ------    =  76k= 24624
304        k            -----  -----------  =      k  =  324
                             76        76


so k is equal to 324

hope this helps have a nice day
