30. ### math

The correct answer is D! We know this because 5 goes into 45 9 times, and 5 goes into 70, 15 times! When finding this fact, you can divide 45 by 9, and 70 by 15. If you get the same number, 5, you'll know it is correct!
31. ### math

C is correct! Like I said when I last helped you, if you divide 25 by 5, and 90 by 18, you will get the same number (5), so that's how you know it is correct!
