A trail mix recipe calls for 3/8 cup almonds and 1/2 cup cashews. What is the total amount of nuts needed for the recipe?

In order to find the total amount of nuts we add the corresponding fractions using the following,
[tex]\frac{a}{b}\pm\frac{c}{d}=\frac{a\times d\pm b\times c}{b\times d}[/tex]apply to the given fractions
[tex]\begin{gathered} \frac{3}{8}+\frac{1}{2}=\frac{3\times2+1\times8}{8\times2} \\ \frac{3}{8}+\frac{1}{2}=\frac{6+8}{16} \\ \frac{3}{8}+\frac{1}{2}=\frac{14}{16} \\ simplify\text{ } \\ \frac{14}{16}=\frac{7}{8} \end{gathered}[/tex]Answer:
there are 7
