Svetradugi [14.3K]

Here is your answer:

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

Hope this helps!
