To determine which of the fractions does not have the same value as the others, we can simplify each one.
- −3/7: This is negative three-sevenths.
- 3/−7: This is three over negative seven, which simplifies to −3/7 (as dividing by a negative gives a negative result).
- −3/−7: This is negative three over negative seven, which simplifies to 3/7 (as the two negatives cancel out).
- −3/7: Again, this is negative three-sevenths, same as the first option.
Now we summarize the simplified values:
- −3/7 = −3/7
- 3/−7 = −3/7
- −3/−7 = 3/7
- −3/7 = −3/7
The fraction that does not have the same value as the others is −3/−7, which simplifies to 3/7.
