    Identify the property shown

    Hi everybody! I need help, I know this is not hard but this is my firstdat homework and I am from india, and I am in america so it's in english. So please help me, it's due in few hours.
    IDENTIFY THE PROPERTY SHOWN:
    5+2=2+5
    6+(-6)=0
    24.1=24
    8.10=10.8
    13+0=13
    7(1/7)=1

    Here is the big one: Find the product. Give the answer with the appropriate unit of measure. Explain your reasoning.
    (90miles/1hour)(5280feet/1mile)(1hour/60minutes)(1minute/60seconds)
    Please answer fast. It's DUE IN FEW HOURS.

    (90miles/1hour)(5280feet/1mile)(1hour/60minutes)(1minute/60seconds)

    [tex]\frac{90miles}{1hour}\times \frac{5280 feet}{1 mile}\times \frac{1hour}{60 minutes}\times \frac{1 minute}{60 seconds}[/tex]

    Now, cancel the units where possible. For instance the hours in the denominator of the first fraction and the hour in the numerator of the 3rd fraction cancel. Do the rest of the canceling. Do the arithmetic with the numbers and you should end up with [tex]132 \frac{feet}{second}[/tex]

    Here are all the CORRECT ANSWERS:
    Multiplicative Inverse
    Additive Inverse
    Commutative Property of Addition
    Commutative Property of Multiplication
    Multiplicative Identity
    Additive Identity
    BUT THEY ARE NOT IN THE CORRECT ORDER!
    You put in the correct order!

    It means that I scrambled the answers. The first listed does not go with the first one in your list. It means that YOU must figure out which goes with which. After all this is your homework not ours. Most of us believe that one should do his own work.
