Which of these numbers are divisible by 9?
7,625 4,932 9,180 2,969
1. 9,180 and 4,932
2. 9,180 and 7,625
3. 2,969 and 4,932
4. 2,969, 9,180, and 7,625
9,180 and 4,932 hope it helps :D
1. 9,180 and 4,932 (they're the only numbers that when divided by 9 don't leave you with a repeating decimal).
thx ash
To add to R_Scott's answer, you can keep adding the digits of the number until you get to a single number. If that number is 9, it is divisible by 9.
So the number 469589013
4+6+9+5+8+9+0+1+3 = 45
45 can be added as 4+5.
So 469589013 is divisible by 9.The answer is 52,176,557.
Thx Ash!
To determine which of these numbers are divisible by 9, you can use a simple rule: if the sum of the digits of a number is divisible by 9, then the number itself is divisible by 9.
Let's apply this rule to each of the numbers:
1. For 7,625: 7 + 6 + 2 + 5 = 20, which is not divisible by 9.
2. For 4,932: 4 + 9 + 3 + 2 = 18, which is divisible by 9.
3. For 9,180: 9 + 1 + 8 + 0 = 18, which is divisible by 9.
4. For 2,969: 2 + 9 + 6 + 9 = 26, which is not divisible by 9.
Therefore, the numbers that are divisible by 9 are 4,932, 9,180, and 7,625. So the correct answer is option 4: 2,969, 9,180, and 7,625.
