Question

4/7+-{4/9}+3/7+{-13/7}​

Answer 1

Step-by-step explanation:

• $\frac{4}{7} + ( \frac{ - 4}{9} ) + \frac{3}{7} + ( \frac{ - 13}{7} )$
• $= > \frac{4}{7} - \frac{4}{9} + \frac{3}{7} - \frac{13}{7}$
• $= > \frac{36 - 28 + 27 - 117}{63}$
• $= > \frac{ - 82}{63}$
• Hence the required answer. Thank you
