Answer:
1.None
2.66,282,294 and 522
3.84
4.126
5.148
6.340
Explanation:
1.We have to find the number which is divisible by 6 but not by 3
We know that divisibility of 6
If a number is divisible by 2 and 3 then the number is divisible bu 6
If a number is divisible by 6 then the number is also divisible by 3.
There is no any number is divisible by 6 but not by 3
2.we have to find the number which is divisible by 6 but not by 12
66,282,294 and 522 are the numbers that is divisible by 6 but not by 12
120 and 204 are divisible by both numbers 6 and 12
314 is not divisible by 6 or not divisible by 12
3.We have to find the smallest integer greater than 79 that is divisible by 12
84 is greater than 79 and smallest integer which is divisible by 12.
4.We have to find the smallest integer greater than 121 that is divisible by 9
We take 126
![126/ 9=14](https://img.qammunity.org/2020/formulas/mathematics/middle-school/fvvlmassdrm98togatha046xzl1b1nj8qn.png)
Hence, 126 is smallest integer greater than 121 which is divisible by 9
5.We have to find the largest number less than 150 that is divisible by 4
148 is largest integer that is less than 150 and divisible by 4
6.We have to find the largest integer less than 341 that is divisible by 5 and 10
340 is the largest number less than 341 which is divisible by 5 and 10.
because a number which is divisible by 10 then the number is also divisible by 5.
