To add these fractions, we need to find a common denominator. The least common multiple of 6, 12, 20, and 30 is 60.
1/6 = 10/60
1/12 = 5/60
1/20 = 3/60
1/30 = 2/60
Now, let's add the fractions together:
10/60 + 5/60 + 3/60 + 2/60 = 20/60
Therefore, the sum of 1/6 + 1/12 + 1/20 + 1/30 = 20/60, which simplifies to 1/3.
Calculation, write the answer in the simplest form and show steps for each.
1) 1/6+ 1/12+ 1/20+ 1/30
