Answer : 212 
Reason why is because yu have 2/5 you multiply it across 8/1 5x1= 5 and 8x2= 16 then you will have 5/16 you divide 5 into 16 , 5 goes into 16 twice then subtract 16 and 10 then you would have 6 bring down the 0 and you have 60 . 5 goes into 60 12 times then you have your answer 212 .

Answer:
Size 50
Step-by-step explanation:
You should choose the larger sample size.  This is because if you take the mean, it will help to cancel out outliers.  For instance, most people exercise half an hour.  With sample size of 10, there might be one person who doesn't exercise, thus dragging down the mean.  A larger sample size would have a greater ratio of "average" people.
 
        
             
        
        
        
3/4 + 1/12 = 10/12 and then you simplify it and get 5/6 as your final answer.
