Question

7/30+9/20 what is the answer pls hurry im so confused

Answer 1

Here is your answer:

• 
  `(7)/(30) + (9)/(20)`
• Find common denominator:
• 
  `30 * 20 = 60 /20 * 30 = 60`
• Common denominator is 60:
• 
  `(7)/(30) + (9)/(20) = (140)/(60) + (270)/(60)`
• 
  `140 + 270 = 410`
• 
  `= (410)/(60)`
• 
  `(410)/(60) / 2 = (205)/(30) / 5 = (41)/(6)`
• =
  `(41)/(6) or 6(5)/(6)`

Hope this helps!
