100% correct
1) To write a fraction as a whole or a mixed number, you divide the numerator (the top number) by the denominator (the bottom number). In this case, the fraction is 39/9.
Dividing 39 by 9 gives you a quotient of 4 with a remainder of 3. So, the whole number part is 4, and the remaining fraction is 3/9.
However, to express the fraction in simplest form, we need to simplify it. Both the numerator and denominator can be divided by 3, resulting in 1/3.
Therefore, the fraction 39/9 as a mixed number in simplest form is 4 and 1/3.
2) To test if a number is divisible by 2, you check if its last digit is even (ends in 0, 2, 4, 6, or 8).
For 62,004, the last digit is 4, which is even, so it is divisible by 2.
To test if a number is divisible by 3, you can add up its digits and see if the sum is divisible by 3.
For 62,004, the sum of its digits is 6 + 2 + 0 + 0 + 4 = 12. Since 12 is divisible by 3, 62,004 is also divisible by 3.
Regarding divisibility by 5, any number that ends with 0 or 5 is divisible by 5. Since 62,004 does not end with 0 or 5, it is not divisible by 5.
For divisibility by 9, you follow the same rule as divisibility by 3. The sum of the digits (6 + 2 + 0 + 0 + 4 = 12) is divisible by 9, so 62,004 is also divisible by 9.
For divisibility by 10, you only need to check if the number ends with 0. In this case, 62,004 ends with 4, so it is not divisible by 10.
Therefore, 62,004 is divisible by 2, 3, and 9, but not by 5 or 10.
3) To check if a number is divisible by 8, you need to determine if the last three digits form a number that is divisible by 8.
For 7,116, the last three digits are 116. Since 116 is not divisible by 8, 7,116 is not divisible by 8.
For 4,309, the last three digits are 309. Again, 309 is not divisible by 8, so 4,309 is also not divisible by 8.
For 4,136, the last three digits are 136. This time, 136 is divisible by 8, so 4,136 is divisible by 8.
Finally, for 9,406, the last three digits are 406. As with the previous numbers, 406 is not divisible by 8, so 9,406 is not divisible by 8.
Therefore, out of the given numbers, only 4,136 is divisible by 8.
I'll be glad to check your answers.
