The total pound of the trail mix will be the sum of the pounds of peanuts, pounds of chocolate candies and pounds of dried fruits.
The following information is provided in the question:
[tex]\begin{gathered} \text{Pounds of peanuts=1}\frac{1}{4} \\ \text{Pounds of chocolate candies=}\frac{2}{5} \\ \text{Pounds of dried fruits=}\frac{3}{20} \end{gathered}[/tex]
Thus, we have:
[tex]\begin{gathered} 1\frac{1}{4}+\frac{2}{5}+\frac{3}{20} \\ \frac{5}{4}+\frac{2}{5}+\frac{3}{20} \end{gathered}[/tex][tex]\begin{gathered} \frac{25+8+3}{20} \\ \frac{36}{20} \end{gathered}[/tex]
By simplifying to lowest terms, decide both the numerator and denominator by 4. We have:
[tex]\begin{gathered} \frac{9}{5} \\ 1\frac{4}{5} \end{gathered}[/tex]
Hence, the correct option is Option A
