Determine the number greater than 70 but less than 85 that is divisible by both 2 and
9. (1 point)
O 84
O 72
O 81
O 78
The number has to be divisible by both 2 and 9.
To be divisible by 2, it must be an even number.
To be divisible by 9, the sum of its digits must be divisible by 9.
The only number between 70 and 85 that meets these conditions is 72, so the answer is O 72.
