stupid
What does prine number means?
If you mean prime number, it is a number which can only be divided by 1 and itself. For example: 2 because only 1 and 2 are the factors of 2 5 because only 1 and 5 are the factors of 5
What number can go into 215?
Do you mean, what is it evenly divisible by? You can answer questions like these by finding the factors of the number and multiplying different factors: 215 ends in 5, so we know 5 is one if its factors. Divide by 5: we're left with 43. 43 is a prime number, it can't be factored any more. 215 is only divisible by 5 and 43. As a better example of how this technique works, consider 100. 100's factors are 5, 5, 2, and 2. By multiplying together different factors, we can discover that 100 is not only divisible directly by its factors 5 and 2, but also by 5*5, 2*2, 5*2, 5*5*2 and 2*2*5.
3and 5 over 8 - 2 and 1 over 4?
3 5/8 - 2 1/4 = 1 3/8
Is 5 a factor of 72?
Answer #1: no==================Answer #2:If you honestly don't know, then here's a little tip that will blow your mind:-- If a number has 5 as one of its factors, then the number ends with a 5 or a zero.-- If a number ends with a 5 or a zero, then 5 is one of its factors.-- If a number doesn't end with a 5 or a zero, then 5 is not one of its factors.
