Answer: Choice B) 45/56
========================================================
Step-by-step explanation:
When we divide two fractions like this, we flip the second fraction and multiply like so...
![(5)/(7) / (8)/(9)\\\\(5)/(7) * (9)/(8)\\\\(5 * 9)/(7 * 8)\\\\(45)/(56)\\\\](https://img.qammunity.org/2022/formulas/mathematics/high-school/pfacpj7e1i30ry9qoyrm236hmp1hpvhnk3.png)
which points us to choice B as the answer.
The fraction 45/56 cannot be reduced further because 45 and 56 do not have any factors in common other than 1.
