Here is your answer:

  • [tex]\frac{7}{30} + \frac{9}{20}[/tex]
  • Find common denominator:
  • [tex]30 \times 20 = 60 /20 \times 30 = 60[/tex]
  • Common denominator is 60:
  • [tex]\frac{7}{30} + \frac{9}{20} = \frac{140}{60} + \frac{270}{60}[/tex]
  • [tex]140 + 270 = 410[/tex]
  • [tex]= \frac{410}{60}[/tex]
  • [tex]\frac{410}{60} \div 2 = \frac{205}{30} \div 5 = \frac{41}{6}[/tex]
  • = [tex]\frac{41}{6} or 6\frac{5}{6}[/tex]

Hope this helps!
