Question 641799


{{{400}}}% you can write as {{{400/100}}} and {{{4/100}}} 

{{{(400/100)5=(4/100)599}}}

{{{4*5=.04*599}}}

{{{20=23.96}}}....not equal

I guess your question should be: why 400% od 5 and 4% of 500 are the same amount

{{{(400/100)5=(4/100)500}}}

{{{4*5=.04*500}}}

{{{20=20}}}....equal

so, why?...because 4:0.04=500:5...inverses
