Which of the following does not have the same value as the other

- 3/7

3/-7

-3/7

-3/-7

3/7

To determine which of the given fractions does not have the same value as the others, we need to compare their values.

Let's simplify the fractions to a common denominator:

- 3/7 (already in simplified form)
- 3/-7 = -3/7
- -3/7 (already in simplified form)
- -3/-7 = 3/7

From the simplification, we can see that the second fraction, 3/-7, is equivalent to -3/7.

Therefore, the fraction that does not have the same value as the others is:

3/-7.

To determine which of the given fractions does not have the same value as the others, we can simplify each fraction and compare them.

The given fractions are:

1) 3/7
2) 3/-7
3) -3/7
4) -3/-7

Let's simplify each fraction:

1) 3/7: This fraction cannot be further simplified.

2) 3/-7: This fraction can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 1. So, 3/-7 is already simplified.

3) -3/7: This fraction is the negative of 3/7, but it has the same value as 3/7.

4) -3/-7: This fraction can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 1. So, -3/-7 is already simplified.

After simplifying all the fractions, we find that -3/7 does not have the same value as the others. Therefore, the answer is -3/7.
