Final answer:

To convert 0.05% into a ratio strength, interpret 0.05% as 0.05 parts per 100 parts. Setting up a proportion (0.05/100 = 1/x) and solving for x gives us a ratio of 1:2000, so the ratio strength of 0.05% is 1:2000.

Step-by-step explanation:

To convert 0.05% into ratio strength we first need to understand the meaning of a percentage as a ratio. By definition, a percentage represents a part per hundred. So, 0.05% means 0.05 parts per 100 parts, or in other words, 0.05 per 100. To convert this percentage to a ratio, it should be expressed in the form 1:x, where x is the number of parts that correspond to one part of the interest substance.

To find x, we can set up a proportion where 0.05 is to 100 as 1 is to x:
0.05/100 = 1/x
0.05 * x = 100
x = 100 / 0.05
x = 2000

Thus, the ratio strength of 0.05% is 1:2000, which corresponds to option c) 1:2000.
