Answer:
[tex] \frac{19}{28} [/tex]
Step-by-step explanation:
distance between -3/7 and 2/8
[tex] = \frac{2}{8} - \bigg( - \frac{3}{7} \bigg) \\ \\ = \frac{2}{8} + \frac{3}{7} \\ \\ = \frac{2 \times 7}{8 \times 7} + \frac{3 \times 8}{7 \times 8} \\ \\ = \frac{14}{56} + \frac{24}{56} \\ \\ = \frac{14 + 24}{56} \\ \\ = \frac{38}{56} \\ \\ = \frac{19}{28} [/tex]
