suppose that A=D+E and that D/A= 0.35 solve for A/E.
substitute in what you can from the info you are given
in this case change 'A' to 'D+E'
this gives us D/D+E =0.35 & D+E/E
see if you can take it from here
sorry I still don't understand
A=D+E , divide each term by A
A/A = D/A + E/A
1 = .35 + E/A
.65 = E/A
E/A = 65/100 = 13/20
Then A/E = 20/13
ok so this would = 1.54
just too see if i got it suppose A=D=E D/A=0.75 would D/E= .25
