Answer: 7 tickets 
Step-by-step explanation:
First you need to remove the cost of entrance from the $45 that Hayden has:
= 45 - 8
= $37
The $37 is the amount that is left for Hayden to be able to buy tickets for the raffle. 
The tickets cost $5 each so the highest number of tickets that can be bought with $37 is:
= 37 / 5
= 7 tickets 
 
        
             
        
        
        

Rationalize.

This can be further simplified to the decimal:
-0.43006...

The least common denominator is 70 because both 14 and 10 go into 70.
 
        
             
        
        
        
If it’s a fraction and want it simplified it’s 1/500
