For this case we must find the value of "n" of the following expression:
[tex]\frac {n} {7} = \frac {5} {\frac {7} {9}}[/tex]
Applying double C on the right side:
[tex]\frac {n} {7} = \frac {9 * 5} {7 * 1}\\\frac {n} {7} = \frac {45} {7}[/tex]
We multiply by 7 on both sides of the equation:
[tex]n = 7 * \frac {45} {7}\\n = 45[/tex]
Thus, the value of n is 45.
ANswer:
[tex]n = 45[/tex]
