Answer:
Option B) a = 1, b = 3, c = 4
Explanation:
We are given the following information in the question:
We are given an expression:
![\displaystyle(7)/(9) / (4)/(9) = a(b)/(c)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/iblhpwvnluj2bbh0f3lqe1ly1jr9hh2sk2.png)
The solving of the above expression can be done in the following manner:
![\displaystyle(7)/(9) / (4)/(9)\\\\(7)/(9)* (9)/(4)\\\\(7)/(4) =((4* 1) + 3)/(4)= 1(3)/(4)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/xe51olt1gk4i3ej3zh4xv3x169ynj58xkm.png)
Comparing the right side of the expression, we have,
![a\displaystyle(b)/(c) = 1(3)/(4)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/hhw97uswysum1h3ou483rhrakqj3fu8gg7.png)
Comparing, we get,
a = 1, b = 3, c = 4
Option B) s the correct option.
