Calculating cumulative frequency using awk

Hi, I wanted to calculate cumulative frequency distribution of my data that involves several arithmetic calls. I did things in excel but its taking me forever. this is what I want to do:
Code:
var1.txt contains n observations which I have to compute for frequency which is given by 1/n and subsequently the cumulative frequency (cumfreq).
obs       freq (1/n)    cumfreq
2            1/7              1/7 
3            1/7              1/7+1/7
4            1/7              1/7+1/7+1/7
5            1/7              1/7+1/7+1/7+1/7
6            1/7              1/7+1/7+1/7+1/7+1/7 
7            1/7              1/7+1/7+1/7+1/7+1/7+1/7 
8            1/7              1/7+1/7+1/7+1/7+1/7+1/7+1/7

Any help on this is very much appreciated. Bunch of thanks in advance.

CPUPOWER-FREQUENCY-SET(1)					  cpupower Manual					 CPUPOWER-FREQUENCY-SET(1)

NAME
cpupower frequency-set - A small tool which allows to modify cpufreq settings. SYNTAX
cpupower [ -c cpu ] frequency-set [options] DESCRIPTION
cpupower frequency-set allows you to modify cpufreq settings without having to type e.g. "/sys/devices/system/cpu/cpu0/cpufreq/scal- ing_set_speed" all the time. OPTIONS
-d --min <FREQ> new minimum CPU frequency the governor may select. -u --max <FREQ> new maximum CPU frequency the governor may select. -g --governor <GOV> new cpufreq governor. -f --freq <FREQ> specific frequency to be set. Requires userspace governor to be available and loaded. -r --related modify all hardware-related CPUs at the same time REMARKS By default values are applied on all cores. How to modify single core configurations is described in the cpupower(1) manpage in the --cpu option section. The -f FREQ, --freq FREQ parameter cannot be combined with any other parameter. FREQuencies can be passed in Hz, kHz (default), MHz, GHz, or THz by postfixing the value with the wanted unit name, without any space (fre- quency in kHz =^ Hz * 0.001 =^ MHz * 1000 =^ GHz * 1000000). On Linux kernels up to 2.6.29, the -r or --related parameter is ignored. FILES
