Express 0.2% as ratio strength?

Answer 1

To express 0.2% as a ratio strength, we need to first understand that a ratio is a comparison of two quantities. In this case, the ratio will compare the amount of the substance in question to the total amount.

To convert 0.2% to a ratio strength, we divide 0.2 by 100 to get the decimal representation: 0.2/100 = 0.002.

Now, let's assume we have a total of 100 units of the substance. The ratio strength would be given as:

0.002:100

This means that for every 0.002 units of the substance, we have 100 units in total.
