Sure, let's find the sum of the series -1 + 1/2 - 1/3 + 1/4 - 1/5 in fraction form.
The series can be written as:
S = -1 + 1/2 - 1/3 + 1/4 - 1/5
To add fractions, we need to find a common denominator. The common denominator for 2, 3, 4, and 5 is 60. So, we'll rewrite each fraction with a denominator of 60:
S = -60/60 + 30/60 - 20/60 + 15/60 - 12/60
Now, combine the fractions:
S = (-60 + 30 - 20 + 15 - 12) / 60
S = -47 / 60
The sum of the series in fraction form is -47/60.
