say for example     from $25 to $10.

the original price was $25, it decreased to $10

so if we use the original price to say it be, the 100% we start from then we could say $\bf \begin{array}{ccllll}
quantity&\%
\\hline\
25&100\
10&x
\end{array}\implies \cfrac{25}{10}=\cfrac{100}{x}$

Now for the second one, you can take 75 and multiply it by two, because 50% means half off.
