Simple, take,

[tex] \frac{24}{n} = \frac{30}{100} [/tex]

cross multiply to get, 

30n=2400

thus,

[tex] \frac{30n}{30} = \frac{2400}{30} [/tex]

n=80.

Thus, your answer is, 80.
Exvited
[tex] \frac{24}{n} = \frac{30}{100} \\ \\ \frac{24}{n} = \frac{3}{10} \\ \\ 24 = \frac{3}{10} n \\ \\ 24 = \frac{3n}{10} \\ \\ 24 \times 10 = 3n \\ \\ 240 = 3n \\ \\ \frac{240}{3} = n \\ \\ 80 = n \\ \\ n = 80 \\ \\ [/tex]

The final result is: n = 80.
