determine wheather 453 is divisible by 3,9
my answer is yes because 3and nine are equally divided by 3,9
is 2,3,4,6,8 divusble by 672
is 3,9 999
is 5200 divisble by 2,5,10
is 504 divisible by 2,4,6,8
453/3 = 151. YES.
453/9 = 50.333333. No, because there
is a remainder.
To determine whether a number is divisible by another number, you need to check if the first number can be divided by the second number without leaving any remainder.
Let's go through each question:
1. Is 453 divisible by 3 and 9?
To check if 453 is divisible by 3, we add up its digits: 4 + 5 + 3 = 12. Since 12 is divisible by 3 (3 × 4 = 12), 453 is also divisible by 3.
To check if it is divisible by 9, we do a similar process. The sum of its digits is again 12, which is divisible by 9 (9 × 1 = 9). Therefore, 453 is divisible by both 3 and 9.
2. Are 2, 3, 4, 6, and 8 divisible by 672?
To determine if each number is divisible by 672, we need to check if 672 can divide each number without remainder. For example:
- 672 ÷ 2 = 336 (no remainder)
- 672 ÷ 3 = 224 (no remainder)
- 672 ÷ 4 = 168 (no remainder)
- 672 ÷ 6 = 112 (no remainder)
- 672 ÷ 8 = 84 (no remainder)
Since each division produces no remainder, all of the numbers (2, 3, 4, 6, and 8) are divisible by 672.
3. Are 3, 9, and 999 divisible by each other?
To check if one number is divisible by another, we divide the first number by the second number and if there is no remainder, then it is divisible. For example:
- 3 ÷ 9 = 0 remainder 3 (not divisible)
- 3 ÷ 999 = 0 remainder 3 (not divisible)
- 9 ÷ 999 = 0 remainder 9 (not divisible)
Therefore, none of the numbers (3, 9, and 999) are divisible by each other.
4. Is 5200 divisible by 2, 5, and 10?
Similar to the previous examples, we need to check if 5200 can be divided by each number without remainder:
- 5200 ÷ 2 = 2600 (no remainder)
- 5200 ÷ 5 = 1040 (no remainder)
- 5200 ÷ 10 = 520 (no remainder)
Thus, 5200 is divisible by 2, 5, and 10.
5. Is 504 divisible by 2, 4, 6, and 8?
Again, we perform division to determine if 504 is divisible by each number:
- 504 ÷ 2 = 252 (no remainder)
- 504 ÷ 4 = 126 (no remainder)
- 504 ÷ 6 = 84 (no remainder)
- 504 ÷ 8 = 63 (no remainder)
Therefore, 504 is divisible by 2, 4, 6, and 8.
