Answer:
it's about 18 percent decrease**** so 20 percent to round up
Step-by-step explanation:
 
        
             
        
        
        
V= LWH so 3.75cm^3 or 3 (3/4)
Multiply those three sides and it comes out to 3.75
 
        
             
        
        
        
So k in the first problem would =1/2
and i guess in the second problem just put k in place of the first space and in the second space put 8 for x. y would then =4. Idk if I did this right, though, I'm honestly a little confused too.

Proportion of games an NFL team wins.
For example, this past regular season, the Buffalo Bills won 13 games out of 16, so the proportion of games won by the Bills is 13/16 = 0.8125.
Other possible examples are:
Proportion of defective products in a shipment.
Proportion of voters of a certain candidate in an election.
