Given:
1/2 loaf of bread
3 friends
1/2 ÷ 3 ⇒ 1/2 * 1/3 = 1*1 / 2*3 = 1/6
In dividing fractions, get the reciprocal of the divisor and multiply it to the dividend
        
                    
             
        
        
        
A = p(1 + rt)
A/p = 1 + rt
rt = A/p - 1
t = (A/p - 1)/r
        
             
        
        
        
If x=1
1/3x = 1/3
3x = 3
If x=2
1/3x=2/3
3x=6
If x=3
1/3x=1
3x=9
If x=4
1/3x=1 1/3
3x+12
        
             
        
        
        
Answer:
Choice D
Step-by-step explanation:
