Problem Solving (PS) | Re: (1/11)+(1/12)+……+(1/19)+(1/20) is including in which of the following

We have a total of 10 elements in the expression.
The minimum range can be got by adding the smallest number
10 times.

Since 1/20 is the smallest number in the expression,
adding the number to the itself 10 times will give you the
smallest number possible(1/20 = 0.05)
When added 10 times to itself, 0.05*10 = 0.5 = 1/2!

Hope that helps!
