Answer:
1/3 of 6 meters is 2 meters
Step-by-step explanation:
 
        
             
        
        
        
1800 laps in 12 weeks
1800/12 = 150 laps in 1 week
150/5 = 30 laps a day
30 laps in 45 minutes
x laps in 60 minutes
x = (30*60)/45 = 40 laps per hour
 
        
             
        
        
        
Two correct answers:
9 + x
x + 9
Or you can say 
x - -9
or 
9 - -x
        
                    
             
        
        
        
30 out of 140
that means the equation is 30/140
that equals .2142 . . .
that moves over the 21%
