If 8 lions is 40% how many would 75% be?

Correct result:

l =  15

Solution:

$$\begin{gathered} p_1=40\mathrm{\%}={\displaystyle \frac{40}{100}}=0.4 \\ {p}_2=75\mathrm{\%}={\displaystyle \frac{75}{100}}=0.75 \\ {p}_1\cdot t=8 \\ 0.4\cdot t=8 \\ 0.4t=8 \\ t=20 \\ l=p_2\cdot t=0.75\cdot 20=15 \end{gathered}$$
