There are three basic division identities you should know about:
1) Zero divided by anything is zero.
(example: 0 ÷ 9 = 0)
2) Any number divided by one is that number.
(example: 9 ÷ 1 = 9)
3) Any number divided by itself is one.
(example: 9 ÷ 9 = 1)
Here are a few examples showing these identities.
9 ÷ 9 = 1 54 ÷ 1 = 54 0 ÷ 9 = 0 0 ÷ 14 = 0 8 ÷ 1 = 8 72 ÷ 72 = 1
