Answer 2

• Given:  $\frac{1}{7}$ - $\frac{3}{4}$
• To solve: To do subtraction, $\frac{1}{7}$ - $\frac{3}{4}$.

      Solution:

• In mathematics, when two numbers that are in fraction are added or subtracted, we first take LCM of the denominators.  
• The LCM of $7$ and $4$ is $28$.
• Therefore, from the given statement we get ,

         $\frac{1}{7}$ – $\frac{3}{4}$ =  $\frac{(4 x 1) - (7 x 3)}{28}$

                 = $\frac{4-21}{28}$

                 = - $\frac{17}{28}$  

                 = -$0.607$.

• Hence, the answer is -0.607.
