REN fine six peanuts, four raisins, 3 cranberries, and 5 chocolate chips in a handful of trail mix. For every 9 pieces in Ren's
tankabanditka [31]

Answer:

2 raisins.

Step-by-step explanation:

Let x represent total number of required ingredient.

We have been given that Ren finds 6 peanuts, 4 raisins, 3 cranberries, and 5 chocolate chips in a handful of trail mix. We are asked to find of which ingredient Ren will have 2 pieces for a total of 9 pieces.

First of all, we will find total number of ingredients by adding each ingredient as:

\text{Total number of ingredients}=6+4+3+5

\text{Total number of ingredients}=18

Now, we will use ratio to solve for our given problem as:

\frac{\text{Required ingredient}}{\text{Total ingredient}}=\frac{2}{9}

\frac{x}{18}=\frac{2}{9}

\frac{x}{18}\cdot 18=\frac{2}{9}\cdot 18

x=\frac{2}{1}\cdot 2

x=4

Since there are 4 raisins, therefore, for  every 9 pieces in Ren's handful of trail mix there are 2 raisins.
