Step-by-step explanation:

First, lets take out some key information in the question:

------------------------

Key information:

388 milliliters

19.7%

------------------------

With the information above, it will make it easier to find the answer for your question.

To find the answer to your question, we would need to find how much is 19.7% of 388 millimeters

Therefore, we would need to multiply 388 and 19.7% to get our answer.

In order for this to work, we would need to move the decimal places to times to the left from 19.7; 19.7 will turn to .197. After you move the decimal place, we can now multiply.

In the question, it asks that we need to round to the nearest tenth, so that's the place right after the decimal place.

The 3 is not a big enoug hnumber to change the number before it, so we would keep the tenth place the same.

It would be rounded up as 76.4

76.4 would be your FINAL answer. There are 76.4 milliliters of acid
