Answer: Choice B) 45/56</h3>
========================================================
Explanation:
When we divide two fractions like this, we flip the second fraction and multiply like so...
![\frac{5}{7} \div \frac{8}{9}\\\\\frac{5}{7} \times \frac{9}{8}\\\\\frac{5 \times 9}{7 \times 8}\\\\\frac{45}{56}\\\\](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B7%7D%20%5Cdiv%20%5Cfrac%7B8%7D%7B9%7D%5C%5C%5C%5C%5Cfrac%7B5%7D%7B7%7D%20%5Ctimes%20%5Cfrac%7B9%7D%7B8%7D%5C%5C%5C%5C%5Cfrac%7B5%20%5Ctimes%209%7D%7B7%20%5Ctimes%208%7D%5C%5C%5C%5C%5Cfrac%7B45%7D%7B56%7D%5C%5C%5C%5C)
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.

![2 \frac{5}{8} \div 2 \frac{1}{2}](https://tex.z-dn.net/?f=2%20%20%5Cfrac%7B5%7D%7B8%7D%20%20%5Cdiv%202%20%20%5Cfrac%7B1%7D%7B2%7D%20)
Change the mixed fractions to improper fractions.
To do this, multiply the whole number part by the denominator. Add that to the numerator. Then write the result on top of the denominator.
You would now have:
![\frac{21}{8} \div \frac{5}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B21%7D%7B8%7D%20%20%5Cdiv%20%20%5Cfrac%7B5%7D%7B2%7D%20)
Change the division sign to a multiplication sign by turning the second fraction upside down.
That is,
![\frac{21}{8} \times \frac{2}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B21%7D%7B8%7D%20%20%5Ctimes%20%20%5Cfrac%7B2%7D%7B5%7D%20)
The answer is:
![\frac{42}{40}](https://tex.z-dn.net/?f=%20%5Cfrac%7B42%7D%7B40%7D%20)
This can be simplified to:
Answer: (m-3)(5m-2)
Step-by-step explanation:
5m^2-17m+6 factored is (m-3)(5m-2).
