Three numbers between 70 and 80 are prime numbers.what numbers are they? Explain how you know they are prime numbers.
A prime number can be divided, without a remainder, only by itself and by 1.
(It must be a positive whole number greater than 1)
Prime nuber betwen 2 and 100 is:
2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97
71, 73, 79..look up the definition of prime for your explanation

To find out which numbers between 70 and 80 are prime, we need to check each number individually to see if it meets the criteria of a prime number.
First, let's define what a prime number is. A prime number is a number greater than 1 that has no divisors other than 1 and itself. In other words, it cannot be evenly divided by any other number except for 1 and itself.
Now, starting with the first number in the range, which is 71, we can check if it is a prime number by dividing it only by numbers less than itself. In this case, we can divide 71 by 2, 3, 4, 5, 6, and so on up to its square root, which is around 8.45. If any of these divisions result in an even quotient (without any remainder), then 71 cannot be prime. However, if we find no even divisors, then it is a prime number.
We repeat this process for the next numbers in the range, which are 73 and 79, using the same divisibility check.
After performing the calculations, we find that 71, 73, and 79 are the three prime numbers between 70 and 80.
