At a certain college the ratio of freshmen to sophomores is 2:3,and the ratio of sophomores to juniors is 5:6.if the ratio of juniors to seniors is 3:5,what is the ratio of freshmen to seniors

• freshmen/sophomores = 2/3
  sophomores/juniors = 5/6
  juniors/seniors =3/5
  
  mulitiplying these three,we get
  freshmen /seniors = 2/3 * 5/6 *3/5 = 1/3
  
  freshmen:seniors=1:3

• freshmen:sophomores=2:3--------->1
  sophomores:juniors=5:6-------------->2
  to make the sophomores in equal ratio multiply equ with 5 n equ with 3
  equ 1-------------> 10:15
  equ 2-------------->15:18
  there fore the ratio to freshmen: sophomores : juniors = 10:15:18
  the ratio for juniors to seniors = 3:5
  to make equal ratio multiply the equation with 6 ---------------->18:30
  freshmen/seniors=10:30 ----> 1:3

• F/So = 2/3 , So/J=5/6 , J/Se=3/5
  
  So, F/J=2/3*5/6= 5/9 & F/Se= 5/9*3/5=1/3
