In plain and short, we simply will divide the whole amount of 2.5lbs by (7+2+5), and then distribute accordingly to each component,

$\bf \stackrel{walnuts}{7}~~:~~\stackrel{peanuts}{2}~~:~~\stackrel{chocolate}{5}
\\\\\\
\stackrel{walnuts}{7\cdot \frac{2.5}{7+2+5}}~~:~~\stackrel{peanuts}{2\cdot \frac{2.5}{7+2+5}}~~:~~\stackrel{chocolate}{5\cdot \frac{2.5}{7+2+5}}$

$\bf \stackrel{walnuts}{7\cdot \frac{2.5}{14}}~~:~~\stackrel{peanuts}{2\cdot \frac{2.5}{14}}~~:~~\stackrel{chocolate}{5\cdot \frac{2.5}{14}}
\\\\\\
\stackrel{walnuts}{\frac{2.5}{2}}~~:~~\stackrel{peanuts}{\frac{2.5}{7}}~~:~~\stackrel{chocolate}{\frac{12.5}{14}}
\\\\\\
\stackrel{walnuts}{\frac{5}{4}}~~:~~\stackrel{peanuts}{\frac{5}{14}}~~:~~\stackrel{chocolate}{\frac{25}{28}}$
