No.
9 is the nearest whole number.
The numbers that will go into both 9 and 100 are their common divisors. The only common divisor between them is 1, since 9 is a multiple of 3 and 100 is a multiple of 2. Therefore, the greatest common divisor (GCD) is 1. In terms of factors, the only number that divides both 9 and 100 evenly is 1.
8.52 rounded to the nearest whole number is 9.
8.525 rounded to the nearest whole number is 9
No, the number 3 is not a multiple of 9. A multiple of 9 is any number that can be expressed as 9 times an integer, such as 9, 18, or 27. Since 3 divided by 9 does not yield a whole number, it does not satisfy the conditions to be a multiple of 9.
