My guess is 75% but I think I did the wrong math good luck
Step by step solving: 
If he collects 32 and she collects 24, then it would be looking for the percentage over 100. 
Rachel. |. 24 
Bruce's 100 |. 32
 % 
 this is the percent one 
you will need to find the percentage over a hundred and 32 is equivalent to one hundred. 
100÷32= 3.125 
24•3.125=75
so in the end, if 32•3.125= 100 then you need to do 24•3.125 as well and you get 75% 
DID I DO THE WRONG MATH!!!!?????
