74 is an even number. It is an even number because one looks at the second digit. If you know that 2, 4, 6, and 8 are even, they you can also find out that 74 is even by constantly dividing it down to a single digit.
No It is not a prime number. There are two ways you can tell its not prime. First of all, their is only one even number that is prime, and the number would be 2. Second, 74 is a composite number, therefor it cannot be prime. Hope it helps you a bit :)
This question has an infinite number of answers. For example, 74/1 = 74 and is a fraction 148/2 also equals 74 as does 7400/100 Treat 74 as your numerator and multiply it by any number, the number you multiplied 74 by is your denominator. 74/1 * x/x = 74 ; where x is any number
Composite Work: A prime number is only divisible by itself and one. 74 is divisible by 2 and 37 Not prime. As soon as you see that '4' at the end, you know it's an even number. No even number (except '2') can be a prime, because in addition to itself and '1', it also has '2' for a factor.
