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 .
Answer:
the answer is -13
Step-by-step explanation:
Step-by-step explanation:
Let the digit at tens place of a two digits number be X
The place value of X = 10×X = 10X
The units digit = 5 more than its tens digit
= X+5
The place value of units digit
= (X+5)×1
= X+5
Now
The two digits number
= 10X+X+5
⇛ 11X+5
Therefore ,The two digits number = 11X+5.
