This really puzzled my students. When we looked at the hint and then the answer, they realized there was a mistake. 8 divided by 4 is 2, not 6.
Thanks! What I meant to say was 8/4=2 and 6/3=2.
That still doesn’t make a true statement, though. Is there something I’m not understanding?
I think so. Instead of 8/4=2 and 6/3=2, you could say 8/4=6/3=2. Also, you can think of it as three parts. Each one equals the same thing. Part one is 8/4 or 2, part 2 is 6/3, or 2, and part 3 is 2.
Some parentheses might help
