1.
The 5/65 can be simplified, the a³ moves to the denominator, and bc is canceled from the numerator and denominator.

2. The 10/125 can be simplified, the a³ moves to the denominator, and bc is canceled from the numerator and denominator.

3. The 65/5 simplifies, the a³ moves to the numerator, and bc is canceled from the numerator and denominator.

4. The 10/130 simplifies, the b² cancels out in the numerator and denominator, and the

moves to the numerator.

5. The 10/130 simplifies, the b² cancels out in the numerator and denominator, the

moves to the numerator, and the

moves to the numerator.

I believe the only expression that simplifies to

is the first one.
