1/2*1/2*1/2*2*2*2 equal 1.  So lets work the problem from let to right.  1/2*1/2 = 1/4 *1/2 = 1/8 *2= 2/8 or 1/4*2 = 2/4 or 1/2*2 = 2/2 or 1.  So just following the typical operations of mathematics from left to right you can see that by multiplying all the numbers equals 1.  You could use the commutative property and group the numbers together to see that you are really multiplying 1*1*1, however both ways in this case provide the same answer.
Multiplication is commutative, which means you can change the order of the numbers. E.g., you can change your problem into:
 
(2*1/2)*(2*1/2)*(2*1/2)
 
If you have 2 halves of a pizza you have 1 pizza; so your problem becomes:
 
1*1*1 = 1
 
"Do you make 2 into 2 over 1?"
 
Yes, you could do that; then you'd use multiplication of fractions:
 
(2/1)*(1/2) = (2*1)/(1*2) = 2/2 = 1
 
Hi Misty;
1/2*1/2*1/2*2*2*2
If you take 1/2 and multiply it by 2, the result is 1.
(1/2)(2)
This can also be written as...
(1/2)(2/1)
Multiply the numerators together, (1)(2)...
Multiply the denominators together, (2)(1)...
2/2=1
In the equation you presented, 1/2 is presented three times and 2 is presented three times.  This is...
1*1*1=1
