Hi
investment of $1500 paid interest of $45 during a certain period
Let x represent interest on an investment of $2000 invested similarly
Question sets Up the Proportion***
  {{{45/1500 = x/2000}}}     | Cross Multiplying 
  1500x = 45*2000
      x = 45*2000/1500
      x = $60, interest on an investment of $2000 invested similarly

CHECKING our Answer***
  45/1500 = 60/2000 = 3/100
