- 5. If the last two digits form a number divisible by 4, then the number is divisible by this number. For example, 316 is divisible by 4 since 16 is divisible by 4.
- 7. this line divides a figure into two halves that are mirror images of each other
- 8. to solve these equations first convert all numbers to the same unit before solving: large to small multiply, small to large divide
- 11. P= 4 x s
- 13. with remainder as a fraction: divide normally, the remainder becomes the numerator and the divisor the denominator
- 15. in=1 ft
- 17. a polygon with 8 sides
- 18. If the last digit is a 5 or a 0, then the number is divisible by this number. For example, 1995 is divisible by this number since its last digit is 5.
- 21. If the sum of the digits is divisible by 3, then the number is also. For example, 177 is divisible by this number since the sum of its digits is 15 (1 + 7 + 7 = 15), and 15 is divisible by 3.
- 22. same shape
