Fractions confusion

Question

2*2

Answer 1

Dear Tatum,

     Draw a number line that starts at zero.   The first number, the 2, represents your number of jumps, and the second number represents how many units in a jump.   Here are some examples:

 

 

 

3X2=6      There are three jumps (groups) with 2 units in each group.

                           

_ .____.____⟩. ___.____⟩.____.___⟩.__________>           3X2     Three groups of 2 (3 jumps of 2units)

0         1        2      3       4       5       6        7

 

                                                                                                

_________>________>_______>_______>______________>        4X2=8    Four groups of two units

0      1      2      3      4      5     6      7     8     9     10

 

 

Usually, there is a half circle mark that goes to each group.  I can only show the mark as the arrow.  If you follow

 

these examples, you can work your problem the same way.

 

If I have helped you, please give me a thumbs up.
