All prime numbers are odd except for the number two. A prime number is defined as any whole number greater than one that has no positive divisors except for one and itself. Since two can only be divided by the numbers one and two, it is prime. <span>The </span>composite numbers<span> are integers having at least two prime factors, whereas a prime </span>number<span> has a single prime factor (itself), and the unit 1 has no prime factors at </span>all<span>. For example, 10 is </span>composite, as it has two prime factors (2 and 5). 11 is notcomposite<span>, since its only prime factor is itself.</span>

A prime number is such that it is divisible by only itself and one. ... Two is a prime because it is divisible by only two and one. All the other even numbers are not prime because they are all divisible by two. That leaves only the odd numbers.

In 2016, 1 out of every 5 people under the age of 50 used a cell phone to read e-books. If there were approximately 225 millio

statuscvo [17]

Answer: 45

Step-by-step explanation:

In 2016, 1 out of every 5 people under the age of 50 used a cell phone to read e-books. This means that 2 out of every 10 people under the age of 50 used a cell phone to read e-books. Also, 3 out of every 15 people under the age of 50 used a cell phone to read e-books.

Therefore, if there were x people under the age of 50 in 2016, then the number that used a cell phone to read e-books would be

1/5 × x = x/5

If there were approximately 225 million people under the age of 50 in 2016, then the number that were likely to have read an e-book on a cell phone is

225/5 = 45 people.
