Am I right?
Three of your answers are wrong.
No. But if you use a calculator, you'll soon find that out for yourself.
oh okay
I believe number one and two are correct and the third to last is true, same with the second and the last one are true. Am I right
To check if a number is divisible by another number, you need to see if the first number can be divided evenly by the second number without leaving a remainder. Let's go through each statement and determine if it is correct:
1. 927 is divisible by 3 and 9: To determine if a number is divisible by 3, you can add up all its digits and see if the resulting sum is divisible by 3. In this case, 9 + 2 + 7 = 18, which is divisible by 3. Therefore, it is correct that 927 is divisible by 3. However, it is incorrect to say that 927 is divisible by 9 since it is not evenly divisible. So the statement is false, not true.
2. 13,012 is divisible by 9: To determine if a number is divisible by 9, you can again add up its digits and check if the sum is divisible by 9. In this case, 1 + 3 + 0 + 1 + 2 = 7, which is not divisible by 9. Therefore, the statement is true since 13,012 is not divisible by 9.
3. 7,434 is divisible by 6: To check if a number is divisible by 6, it needs to be divisible by both 2 and 3. In this case, 7,434 is not evenly divisible by either 2 or 3. Therefore, the statement is false.
4. 2,064 is divisible by 2, 4, and 8: It is correct that 2,064 is divisible by 2 since it is an even number. However, it is incorrect to say that it is divisible by 4 and 8 because it is not divisible by 4. Therefore, the statement is false.
5. 96,240 is divisible by 2, 3, 5, and 10: To check if a number is divisible by 10, you need to verify if it ends in a zero. In this case, 96,240 does end in zero, so it is divisible by 10. However, it is not divisible by 2, 3, or 5 since it does not meet the criteria for those numbers. Therefore, the statement is false.
Based on the explanations above, here are the correct answers:
1. False
2. True
3. False
4. False
5. False
