A. 6/5

B. 5/6

C. 5/24

D. 1/5

E. 1/12


Solving the denominator we get deno=10/24 and num=1/2 ,
So num/Deno= 6/5

Ans A

A. 6/5

B. 5/6

C. 5/24

D. 1/5

E. 1/12


1/4 + 1/6 = 3/12 + 2/12 = 5/12

(1/2)/(5/12) = (12*1)/(5*2) = 12/10 = 6/5

Answer choice A.

Remove 1/2 Common from denominator

1/2 numerator and denominator gets cancel and we are with 1/(1/2+1/3)

1/(5/6) ==> 6/5

Hence A

\(\frac{\frac{1}{2}}{\frac{1}{4} + \frac{1}{6}} = \frac{\frac{1}{2}}{ \frac{10}{24}} = \frac{24}{10} * \frac{1}{2} = \frac{12}{10} = \frac{6}{5}\)

IMO A
