What is 81 over 9 as a whole number
3
There is no whole number - 81/90 in its simplest form is 9/10 !
They are -9 and 9.
9/2 can't be a whole number.
Examples of such numbers are 49, where sqrt(49) = 7, 81, where sqrt(81) = 9. Such numbers are called square numbers.
No because 7/9 is a fraction which is not a whole number
9
There is no whole number - 81/90 in its simplest form is 9/10 !
Factors are just numbers 81 can be divided by. The whole number factors are 1, 3, 9, 27, and 81
They are -9 and 9.
9 (92 = 81)
9/2 can't be a whole number.
The square number of 81 is 9. 9 x 9 = 81
9/24 is not a whole number, so no whole number is equivalent to it.
no it's not a whole number.
Examples of such numbers are 49, where sqrt(49) = 7, 81, where sqrt(81) = 9. Such numbers are called square numbers.
No, 82 is not a multiple of 9 because 9 can not be multiplied by any whole number to get 82. (9x9=81, 9x10=90, there is no 82 in between).
92 = 81 and 102 = 100 so the square root of any number between 81 and 100 would lie between 9 and 10.
