Answer 2

Answer:  The correct option is (A) $7\dfrac{1}{24}.$

Step-by-step explanation:  We are given to perform the following indicated operation :

$E=1\dfrac{2}{3}+5\dfrac{3}{8}~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

We will be using the following rule :

$a\dfrac{b}{c}=\dfrac{ac+b}{c}.$

From (i), we get

$E\\\\=1\dfrac{2}{3}+5\dfrac{3}{8}\\\\\\=\dfrac{5}{3}+\dfrac{43}{8}\\\\\\=\dfrac{40+129}{24}\\\\\\=\dfrac{169}{24}\\\\\\=7\dfrac{1}{24}.$

Thus, the required answer is $7\dfrac{1}{24}.$

Option (A) is CORRECT.
