Since .25*10 is 2.50 and .10*15 is 1.50 it equals $4. So the ratio is 10:15 which turns to 2:3 ratio simplified.
 
        
                    
             
        
        
        
(8/9)^2 is just 8/9 squared, or 8/9 * 8/9. This is 64/81, and cannot be reduced. This is therefore our answer.
 
        
                    
             
        
        
        
Answer:
   2.48×10^13 miles
Step-by-step explanation:
There are about (365.25 days)(86400 seconds/day) = 31,557,600 seconds in one year. There are 1609.344 meters in one mile. So, the conversion can be written as ...
   (4.22 ly) (3×10^8 m/s) (3.15576×10^7 s/yr) / (1.609344×10^3 m/mi)
   = 4.22×3×3.15576/1.609344×10^(8+7-3) mi
   ≈ 24.8×10^12 mi
4.22 light years is about 2.48×10^13 miles
