will medal and fan What property is shown by the equation? Column A 1. –24 • 0 = 0 2. 1/16x(16)=1 3. –18 • (–1) = 18 4. 5 ÷ (–1) = –5 Column B A. Reciprocal Property of Multiplication B. Identity Property of Division C. Negative One Property of Multiplication D. Zero Property of Multiplication E. Negative One Property of Division

Okay, so let's solve the first one together. What do you think the first one is based on its context?
a
What property states that any number multiplied by 0 is always 0?
d
So which number does that go along with?
1
Correct. Now number two says that 1/16 x 16/1 = 1. Which letter would that be?
1d 2? 3? 4?
c
I would have to disagree with ya' on that one. Which property states that the opposite of a number multiplied by itself is 1?
e
We're not really dividing here, and it doesn't have a -1 in it. Which other one could it be?
b
Okay, it would be letter A and here's why: Reciprocal means that the opposite of a number multiplied by itself if 1. I'll show you the example: \[\frac{ 1 }{ 16 } * \frac{ 16 }{ 1 } = \frac{ 16 }{ 16 } = 1\]
ok 1d 2a
3? 4?
Before I go further, are you understanding this or just looking for the answers?
im understanding it i alreday had the frist one correct
Okay, so number 3 would be the one that multiplied by -1 is either a double negative or the opposite of the number. Which property is that one?
a
right?
You're already stated that a is an answer. Which property states something about "-1"? Key word: -1
You've*
you can use it more then one time
Even if you can, that's not the correct answer. Which property states about multiplying with negative one?
oh d
That states that any number multiplied by 0 = 0. 18 * (-1) = -18 Which property states about multiplying negative numbers?
ok?
e
You're almost there, but that's division. We're doing multiplication.
dang it
Which one states about multiplying negative numbers?
C!!!!!!
Correct! Now I've noticed that number 4 is left out. What does number 4 state?
5 ÷ (–1) = –5 e
