One example of three consecutive odd numbers is 1, 3, 5.
What do you get when you divide 111 by 3?

You mean...
37+37+37 = 111
37+37+37 = 111
Ms. Sue
True.
You need three different numbers. They must be consecutive odd numbers. 37 is one of these numbers. What are the other two?

That easy??? I thought that it will be a kind of equation question???
Can I use this 3 numbers?
49+33+29=111
Can I use this 3 numbers?
49+33+29=111
Cassidy
Oh I messed up...now I get it,
37+71+3=111
Right?
37+71+3=111
Right?
Ms. Sue
The three numbers need to be consecutive. That means there are only two numbers between each of the three numbers.
Remember three consecutive odd numbers are 1, 3, 5
You found one of the consecutive odd numbers. It's 37. What is 2 less than 37? What is 2 more than 37?
Do those three numbers add up to 111?

Oh I see, which means is 35+37+39=111
And the question is asking what is the smallest of the three numbers, is that the number of 35?
