Hey There Luci,
What fraction of a pound is forty pence?
<span>40/100, which can be simplified to 4/10, which can be simplified further to 2/5</span>
        
                    
             
        
        
        
Ruby's hours will represent x+6
Svetlana's hours will represent 4(x+6)
Issac will represent x. 
The equation would read:
x+(x+6)+(4(x+6))=126
x+x+6+4x+24=126
6x+30=126
Subtract 30 from both sides. 
6x=96
Divide 6 on both sides to get x by itself.
x=16
So:
Issac worked 16 hours
Ruby worked 22 hours
Svetlana worked 88 hours. 
To check your answer, plug in the values:
16+22+88=126
126=126
Hope this helps.
        
             
        
        
        
You can plot this by turning the fraction into a decimal. -1&1/3rds is -1.333... and 1/6ths is about .16, so then you can find these points on the number line. Also, the number line has 6 points equal one, so the points by those.
 
        
                    
             
        
        
        
Answer:
4.63
Step-by-step explanation:
4/5 of an hour is 48 minutes
1 4/5 hour is 60 + 48 
which is 
108 minutes
he ran 8 1/3 miles in 108 minutes
so
(8 1/3 times 60 ) ÷ 108
which = 
4.6296296296 miles in one hour
