\(\frac{\frac{1}{2} + \frac{1}{3}}{\frac{1}{4}}=(\frac{1}{2} + \frac{1}{3})*4=(\frac{3+2}{6})*4=\frac{10}{3}\).

\(\frac{\frac{1}{2} + \frac{1}{3}}{\frac{1}{4}}= 4(\frac{5}{6}) = \frac{10}{3}\). Ans - E.

Here's an approach that uses approximation

Given: (1/2 + 1/3)/(1/4)

1/2 + 1/3 = a little less than 1 so we can write: (a little less than 1)/(1/4)

We know that 1/(1/4) = 4

So, (a little less than 1)/(1/4) = a little less than 4

Since only one answer choice (E) is greater than 1, it is the ONLY answer choice that's reasonably close to a little less than 4

We can multiply the given expression by 12/12 and we have:

(6 + 4)/3 = 10/3

Answer: E
