No.
no
Yes, 320 / 5 = 64
Yes. 320 / 10 = 32
No. 320 is not evenly divisible by nine.
320, for example
No. Nor is it a multiple.
Well, let's take a moment to look at this question. To see if a number is divisible by 3, you can add up the digits and see if that sum is divisible by 3. For 780, 7 + 8 + 0 = 15, which is divisible by 3. But for 320, 3 + 2 + 0 = 5, which is not divisible by 3. So, 780 is divisible by 3. Now, to check if a number is divisible by 5, you can see if the last digit is 0 or 5. In this case, 780 ends in 0, so it's divisible by 5. However, 320 does not end in 0 or 5, so it's not divisible by 5. So, 780 is divisible by both 3 and 5, while 320 is only divisible by 5.
4, 80, 1, 320, 5, 64, and infinite other numbers, including decimals
160, 320, 480, 640, and all other multiples of 160 are divisible by 160.
No, it is divisible by many numbers including 2 and 320.
320 is divisible by 2, 4, 5, 8 and 10. Those are only the whole numbers, though. It can be divided by 2, 3, 4, 5, 6, 7, 8, 9 and 10, but it equals a decimated number. 320/2=160. 320/3=106.666666667. 320/4=80. 320/5=64. 320/6=53.3333333333. 320/7=45.7142857143. 320/8=40. 320/9=35.5555555556. 320/10=32. So, technically, 320 can be divided by every number, even ones higher than it (for example, 320/1234=0.25931928687). I dislike mathematics because of this large complication. So, in the end, you should have asked "What is 320 divisible by in whole numbers: 2, 3, 5, 9 or 10?" because this also would have been correct in English grammar. Hope this helps and doesn't just confuse you like it does to me... he he.
