one percent is 1% (百分之一) one tenth is 1/10 (十分之一) First, get the number for the 1% =? then get the number of 1/10 from ? For example, if the total number =100, 1% = 1 from this number 1 (1%), take 1/10, it is 0.1

less than one-tenth of 1 percent of all milk tests positive for animal drug residue less than the tenth part of 1% of all milk tests positive for animal drug residue eg: if the total of the milk tests positive for animal drug residue is 20, (1% of 20= 0.2) so : less than 0.02 of all the tests...

Another way to think about it. Imagine 10,000 cartons of milk in a building. We will have scientists test them all. First, I will put the cartons in groups in 100 different labs. So each lab will have 100 cartons of milk (100 x 100 = 10.000). ONE lab found animal drug residue. NInety-nine labs found no drug residue. Only 1 lab out of 100 found it. That represents 1% of the milk. Now, we go inside this one lab. We have ten tables. Each table has 10 cartons of milk on it (10 x 10 = 100). The scientist found drug residue in the milk on ONE table. He did not find any in the milk on NINE tables. That represents 1/10th of his milk (or 10% of his milk). His room of milk was 1% of all the milk in the building. And now 1/10th of his milk showed drug residue. SO, "one-tenth of one percent of all the milk" had drug residue. Now, let's go over to his ONE table. He tests the 10 cartons. He finds drug residue in 8 cartons. Two are OK. This is LESS THAN all the milk on the table. So, overall, "less than one-tenth of one percent of all the milk" showed drug residue.

one-tenth of 1 percent = 0.1% :D

it is two formulas! a= 1 percent ot all milk. [here milk is supposed to be 100%] b=1/10 of "a" [1/10 = 0.1] next a= 0.01 part of all milk b. 0.1 of "a" so b = 0.001 part of all milk! here the volumn of milk must be given!
