To add these fractions together, the first step is to find a common denominator. The denominators in this case are 20 and 15. The lowest common multiple of 20 and 15 is 60.

Next, we need to convert each fraction so that it has a denominator of 60.

3/20 can be converted to 9/60 by multiplying the numerator and denominator by 3 (20 x 3 = 60).

7/15 can be converted to 28/60 by multiplying the numerator and denominator by 4 (15 x 4 = 60).

Now that the fractions have a common denominator of 60, we can add them together.

2 + 9/60 + 1 + 28/60 =

The whole numbers (2 and 1) can be rewritten as fractions with a denominator of 60:

2 = 120/60 1 = 60/60

Now we can add the fractions:

120/60 + 9/60 + 60/60 + 28/60 =

Therefore, 2 + 3/20 + 1 + 7/15 = 149/60.
