No 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88. 81 is not a multiple of 8.
14. 14*8-81=31. or (31+81)/8 = 14
it is 81 because you divide it by 8
81; each number is a factor of 81, and it is the smallest you can get.
The answer depends on what you mean by higher. 81 is bigger than 64. But the square roots of 81 are -9 and +9 while the square roots of 64 are -8 and +8. You then have -9 < -8 so sqrt(81) < sqrt(64) -9 < 8 so sqrt(81) < sqrt(64) -8 < 9 so sqrt(64) < sqrt(81) 8 < 9 so sqrt(64) < sqrt(81) Take your pick!
81 times 8 = 648
81 / 8 = 10 with a remainder of one. So 81 / 8 simplified is 10 1/8.
8/81 can't be simplified any further.

8/81 is already in simplest form. The only common factor between 8 & 81 is 1.
It is: (8*10)+1 = 81
No 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88. 81 is not a multiple of 8.
It is: 8/9 of 81 = 72
No, it does not.
5 over 8 is bigger (1/8 bigger)
