Response to The ambigity of "dilution 1:3"

Mathematically 1:3 is a ratio, which usually associated with mulitplication or division, to interpret 1:3 as 1+3 is incorrect.

1:3 = 2:6 =3:9 = 0.33333

To interpret "a RATIO of 1 to 3" as "1 plus 3" is clearly incorrect. Because 1:3 =2:6 =0.33333 never = 1+4

I much prefer the usage dilute 1 part stock + 3 part water
