Answer 1

1/4+4/7+7/10+10/13+13/16+16/19+19/22+22/25+25/28+28/31+31/34+34/37+37/40 = 10.2406675
40/43+43/46+46/49+49/52+52/55+55/58+58/61+61/64+64/67+67/70+70/73+73/76 = 11.3755706
76/79+79/82+82/85+85/88+88/91+91/94+94/97+97/100 = 7.73024516
10.2406675+11.3755706+7.73024516 =29.34648326

#include <stdio.h>
int main ()
{
int deon,mole;
double sum,term;
sum=0;
for(deon=4;deon<=100;deon+3)
for(mole=1;mole<=97;mole+3)
term=mole/deon;
sum=sum+term;
printf("sum=%lf",sum);
}
