Answer 2

$\fontsize{18}{10}{\textup{\textbf{The value of the expression is }}}\dfrac{121}{35}.$

Step-by-step explanation:

We are given to simplify the following expression :

$E=1\left(\dfrac{3}{5}\right)+5\left(\dfrac{4}{7}\right).$

Since the denominators of both the fractions are different, we need to take LCM of the denominators.

The simplification is as follows :

$E\\\\\\=1\left(\dfrac{3}{5}\right)+5\left(\dfrac{4}{7}\right)\\\\\\=\dfrac{3}{5}+\dfrac{20}{7}\\\\\\=\dfrac{21+100}{35}\\\\\\=\dfrac{121}{35}.$

Thus, the required simplified value is $\dfrac{121}{35}.$
