When written as the quotient of two integers,
           0.69696969  =  <em>69,696,969 / 100,000,000 .</em>
<u>If</u> you had said that the ' 69 ' keeps repeating forever and never ends,
then that decimal would represent the fraction
                                                                       23 / 33 .
                                                     
        
             
        
        
        
You use the Pythagorean theorem which is a^2+b^2=c^2
So....
.8^2+.6^2=c^2
.64+.36=c^2
1=c^2
1=c becaaue the square root of one is one
        
                    
             
        
        
        
The answer is -1 , because when you add a negative number to a positive number the negative number will subtract , and vise versa.
