Sav [38]

Answer:

\frac{5}{7}-(-\frac{1}{7})=\frac{6}{7}

Step-by-step explanation:

To evaluate :

\frac{5}{7}-(-\frac{1}{7})

Solution:

Two negatives multiply to become a positive.

Thus, we can remove parenthesis by reversing the signs of the fraction by multiplying the negative outside.

⇒ \frac{5}{7}+\frac{1}{7}

Since the denominators are same for both fractions, so we simply add the numerators.

⇒ \frac{5+1}{7}

⇒ \frac{6}{7}  (Answer)
