Answer 2

Answer:

=> $-\frac{18}{133}$

Step-by-step explanation:

Given expression -

$\frac{2}{7}-\frac{8}{19}$

As we have to evaluate the above expression,

First, we have to find the lowest common denominator:

$=>\frac{2\times 19}{7\times 19}+\frac{-8\times 7}{19\times 7}$

Now, multiply both the numerator as well as the denominator we get-

$=>\frac{38}{133}+\frac{-56}{133}$

Combining the fractions:

$=>\frac{38+(-56)}{133}$

Adding the terms in the brackets:

=> $-\frac{18}{133}$

Hence, the required value we get $-\frac{18}{133}$.
