Question

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?

Answer 1

In order to find the total amount of nuts we add the corresponding fractions using the following,

`(a)/(b)\pm(c)/(d)=(a* d\pm b* c)/(b* d)`

apply to the given fractions

`\begin{gathered} (3)/(8)+(1)/(2)=(3*2+1*8)/(8*2) \\ (3)/(8)+(1)/(2)=(6+8)/(16) \\ (3)/(8)+(1)/(2)=(14)/(16) \\ simplify\text{ } \\ (14)/(16)=(7)/(8) \end{gathered}`

Answer:

there are 7
