What is four ninths plus twenty-twenty sevenths?

Answer 1

4/9 + 20/27

you must find a common denominator to add. 27 is a good one for this problem, because 9 goes into 27 evenly and you won't need to change the second fraction

4/9 -> x/27 9 * 3 = 27 4 * 3 = 12

4/9 = 12/27

now, you can add 12/27 and 20/27. do not add the denominators, only the numerators

12 + 20 = 32

32/27

if you want a mixed number, the answer would be 1 5/27
