Answer 1

Answer:

417 is the number of adults that would erase their personal information online if they could, they are the 61%. The complete number is 417,85, but we have to adjust the answer for people.

Step-by-step explanation:

To find the answer we need to do a Rule of Three. The Rule of Three is a Mathematical Rule that will help us to solve problems based on proportions.

1. I know that a 685 adults were surveyed, so this is the 100%. 61% say they would erase all of their personal information online if they could, and we don't know the numbre of people in here.

2. So 685 adults _____ 100%

            X adults  _____ 61%

Here we have to put the same elements in the same columns. Students with studients and percentage with percentage.

3. Now I have to cross these details. I have to multiple 61*685. So:

61*685= 41785

4. Then divide that result by 100.

41785/100= 417,85

5. So 417 is the total number of adults that would .
