Best Helper #1

The below blog post was created by a student.  Please see answers in green.
**************************************************************************************************
Answer these questions please.
 
1. Jim had three spider legs. He ate all of them.  How many legs are left? Explain?

3 subtract 3 equals zero.  He had zero spider legs left.  The reason he had zero left was because he ate them, and so the result was less than what he started.

2.  60/2,133
2,133 rounds to 2,000.  So, 60/2,000 simplifies to 6/200 which is equal to 3/100 or 0.03.  Unless you meant:  2,133/60  The answer to 2,133/60 equals:  355 1/2  or 355 R. 3


3.   9,111
      x600
     5,466,600

There was no need to do number 3 by long multiplication because multiplying by 600 can easily be completed by mental math.  First, you multiple 9,111 by 6.  Then add two zeros to the answer.
