To determine the number that is greater than 70 but less than 85 and divisible by both 2 and 9, we can follow these steps:
1. Start by finding the smallest number greater than 70. In this case, it is 72.
2. Check if this number is divisible by both 2 and 9.
- To check if a number is divisible by 2, we need to see if it is an even number. In this case, 72 is even.
- To check if a number is divisible by 9, we need to find the sum of its digits. If the sum is divisible by 9, then the number is divisible by 9. In this case, 7 + 2 = 9, which is divisible by 9.
3. If the number passes both divisibility tests, then it is the answer.
4. If the number doesn't pass one or both of the tests, we move on to the next number.
5. Repeat steps 2-4 until we find the correct number.
Following these steps, we can determine that the number greater than 70 but less than 85 and divisible by both 2 and 9 is 72.
