Answer:

For (a)

(-13/20)+11/14+(-5/7)-7/10

  • (-13/20)+11/14-5/7-7/10
  • [-91+110-100-98]/140
  • [-189+110-100]/140
  • [-289+110]/140
  • [-179/140]
  • so -179/140

For (b)

  • 4/5+-(-8/9)+(-5/15)+1/3
  • 4/5+8/9-5/15+1/3
  • [36+40-15+15]/45
  • [76-0]/45
  • so 76/45

i hope this will help u!
