Write your question here (keep it simple and clear to get the best answer)the medal zena won for athletics consists of silver and brass in the ratio 3: 5.if the medal has a mass of 200g how do i calculate the mass of the silver?

Silver : brass = 3 : 5
Lets take the value as x

Therefore, 3x+5x = 200     ( since the mass of the medal is 200 g )
                       8x  = 200
                         x  = 200/8
                             = 25

The mass of silver = 3x
                              = 3*25
                              = 75 g
