choose all fractions equivalent to each given fraction

For a, 7/-8 and -(7/8) are both equivalent to -7/8 because they have 1 negative sign. It doesn't matter where it is on the fraction as long as there is only 1 negative sign.
For b, -2/-3 is equivalent to 2/3 because the double negatives cancel each other out to equal a positive.
Answer:
[tex]\frac{-7}{8}[/tex] = [tex]-\frac{7}{8}[/tex]
[tex]\frac{2}{3}[/tex] = [tex]\frac{-2}{-3}[/tex]
Step-by-step explanation:
the negative can just move down on -7
the negatives cancel out on -2/-3 to make 2/3
