Math question: If the number 7822 is divided by 6 and then multiplied by 4, what is the result?

To find the result, we first divide 7822 by 6, giving us 1303.6666... (recurring). Next, multiplying this by 4, we get 5214.6666... (recurring). Rounding this to the nearest whole number gives us the answer of 5215. Therefore, the result of dividing 7822 by 6 and then multiplying by 4 is 5215.

Math question: How many prime numbers are there between 2 and 7822?

To find the number of prime numbers between 2 and 7822, we can apply the Sieve of Eratosthenes method. First, create a list of numbers from 2 to 7822. Then, starting from 2, eliminate all its multiples. Next, move to the next non-eliminated number, which is 3, and eliminate its multiples. Repeat this process until you reach the largest number, 7822. Finally, count the remaining non-eliminated numbers, which are prime. By following this method, we find that there are 1008 prime numbers between 2 and 7822.
