1 1/9
To figure out how much walnuts to a pound of dried fruit you’d need to do proportions. So we cross multiply:
2/3 = X
—————- —————- 
3/5 = 1
You multiply diagnols 2/3 x 1 = 2/3
3/5 times x is 3/5x. 
2/3 = 3/5x. Isolate the variable. Divide 3/5 on both sides cancel out 3/5. 2/3 divide by 3/5 is 2/3 x 5/3 which is 10/9 which equals 1 1/9.
So for 1 lb of dried fruit you need 1 1/9 lb of walnuts to maintain the same mixture
        
             
        
        
        
Answer: Randomly assign the 1,200 students to <u>6 equal-sized</u> groups. Then select one of the groups and place their names in the bin. Randomly select the winner from the bin.
Step-by-step explanation:
      First, let us see how many bins we will need in total.
1,200 students / 200 notecards per bin = 6 bins 
      Now, the first two options do not give all students a fair chance of winning. They are not our answer.
      The last two have a different number of groups. Looking at the calculation we did earlier, we will need 6 equal-sized groups. This means our answer is the last option.
 
        
             
        
        
        
The answer is 1.6632. Using a calculator will help you out a lot :)
Still, hope this helps :)
