First, convert 3/5 to a percent by multiplying it by 20/20, getting 60/100, or 60%. Then, find 60% of 40 by multiplying 60 by 40 to get 2,400 and divide it by 100 to get 24, meaning Mark spend $24 on both books. Each of the books cost $12, as 24/2 is 12.

36 to R AND B
36/5=7.2
7.2x2=14.4 for Roger
7.2x3=21.6 for Bethan

To find the solution to this problem, you would do the opposite of division which is multiplication. 
Use the terms you have to plug into your new equation; 
0.6 x 1.4 = .84
To check your work you would plug in .84 where the '?' is; 
.84/.6= 1.4
There you have the original equation you began with.
Therefore, .84 would be your final answer. 
        
             
        
        
        
Answer:
2 feets 
Step-by-step explanation:
Given that :
Alli's Initial depth = 6 feets
Number of feets in which Alli rose = 4 feets
Alli's new position relative to the surface of the pool:
Difference of Alli's initial depth and feets risen :
6 feets - 4 feets = 2 feets
Hence, Alli is now 2 feets below the surface of the pool.
