Answer:
B, C, D, F
Step-by-step explanation:
to simplify the fraction 48/64, you need to divide both the numerator and denominator by their common factors. B is correct since you can divide both by 16, C is correct since both are divisible by 8, D is correct since both are divisible by 4, and F is correct since both are divisible by 2. A, however, would be correct only if the fraction were 64/48 and E would only be correct if 9 was a factor of 48 and 12 was a factor of 64, however neither haev such factors.  
 
        
                    
             
        
        
        
Answer: With that assumption, we have a square, whose area is given by the formula Asquare=a2, and two semicircles. The distance D is simply the square's diagonal. The area of each semicircle is given by the formula Asemicircle=π*r2/2. then you will get your answer!

Step-by-step explanation:
n(S) = 25
Assume that O : odd numbers and E : even numbers, 
n(O) = 13
n(E) = 25-13 = 12
P(OO) = P(O) x P(O) 
 = 13/25 x 12/24
 (because without replacing so the number of balls left decreases) 
 = 13/25 x 1/2
 = 13/50
