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

Then, you take the total which is 72, and divide it by how many numbers you added together which is 5.
72/5 = 14.4
