    Step-by-step explanation:

     \frac{ - 2}{3} -   \frac{ - 5}{7}

    lcm \:  = 21

     \frac{ - 2 \times 7}{3 \times 7}  =   \frac{ - 14}{21}

     \frac{ - 5 \times 3}{7 \times 6}  =  \frac{ - 15}{21}

     \frac{ - 14 - (-15 )}{21}  = \frac{ - 14  +  15 }{21}

     =  \frac{1}{21}

    hope it will help you
