(Mishnah): If a person wishes to separate Terumah (1/50th=2%) and Terumas Maaser (1/100th=1%) at the same time, he should take 1 part of 33 1/3rd (i.e. 3%) and say, "One hundredth of what is here (i.e. 1% of the total) that is on this side should be Chulin. And the rest (of what I've taken i.e. 2%) should be Terumah for the whole mixture. And the 1/100th (of the total) that I said (originally) is Chulin that is on this side should be (part of the) Maaser and that (additional 9%) that is next to it should be the rest of the Maaser. That (1%) that I made (part of the) Maaser shall be Terumas Maaser for it and the rest shall be Challah and the Maaser Sheni shall be on its northern or southern side and should be redeemed onto the coins.

(Gemara) (Baraisa): If a person wishes to separate Terumah, Terumas Maaser and Challah at the same time, he should take a portion enough for all of them together, which is 1/20th (5%) of the mixture, and he should say, "1/100th of the entire mixture that is on this side should be Chulin Tevel; another 1/48th next to it should be Chulin and the rest (of what I have taken) is Terumah for all of it; and of the Chulin, this that I made Chulin Tevel should be (part of the) Maaser and the rest of the Maaser should be next to it; and this that I made Maaser should be its Terumas Maaser and the rest is Challah and its Maaser Sheni should be on its northern or southern side and is redeemed onto the coins.
