# Thread: Need help with loop problem

1. ## Need help with loop problem

I need help with a problem for class. the Problem is :
Q10: Write a for loop to sum the following series: (1 /2) + (2/3) + (3/4) + … + (49/50).

my code so far is
```public class forlooptest {

public static void main(String[] args) {
int a = 1;
int b = 2;
int x = (a/b);
for (a=1, b=2;a>49 ; a++,b++){

x = (a/b)*50));

}

}

}```

Any help would be greatly appreciated

2. ## Re: Need help with loop problem

Look at the series of fractions. What is the relationship between the values in one fraction and the next one?
How can that relationship be used in a loop for solving the problem?

The first thing you need to do is use doubles. int arithmetic will lose the fractional part: 3/4 = 0
