Question

divide the sum of rational numbers 2/5 and -7/11 by their product​

Answer 1

Step-by-step explanation:

$\frac{2}{5} + \frac{ - 7}{11} \div \frac{2}{5} \times \frac{ - 7}{11} \\ = \frac{22}{55} + \frac{ - 35}{55} \div \frac{ - 14}{55} \\ = \frac{ - 13}{55} \div \frac{ - 14}{55} \\ = \frac{ - 13}{55} \times \frac{55}{ - 14} \\ = \frac{13}{14}$
